Griefing in Ban Phase

Alright so I'll be rather blunt here. This is an issue that is either very or moderately frequent, specifically the cases where an ally bans your champion. Let's go over the scenarios, if it's them banning your champion when you haven't even selected or stated it, then it is your fault for not highlighting it on time when you have 15 seconds. The scenarios I'm concerned over though are the ones in which an ally does this, while knowing you intend to play them for a different reason. Several times, I've had scenarios where someone wants to trade with me in the draft pick which isn't a strange occurrence in any way and is fine, but in said scenarios, about a third of the time when i decline and have highlighted a champion, they ban said champion; to spite you, to get you to rage quit the champ select so they have another chance at their role, either way they grief, in a way in which they ruin your game as you will be time banned if you skipped, MMR and points will be reduced if it's a ranked game and there is no way to escape this or for them to be disciplined for it, for they can only laugh at you as things go their way while the rest of the team usually doesn't care or tell you the all too standard ''chill'' and ''stop cry/crying'' quotes they've so well memorized. Another scenario, is them disagreeing with your pick. It doesn't matter if it's due to them thinking it's a low win rate champion, a non-meta choice or that you're too late of a pick and they don't want the risk of the enemy getting the champion you want to play instead since they don't like playing against said champion. Now, in the last of those scenarios, at least there's some logical reason. Acceptable? I'd highly disagree. But at least they're thinking and i can't really be that mad over it. In the other two, they're just being a bunch of jerks, ruining your chance to play something you want, ruining your fun, much like the first one, they're screwing you over for their own pleasure while treating you as something below them, glaring at you daring to have an opinion or wanting to play this or that uncharacteristic pick. In said last scenario, the team aside from not caring, can outright be hostile, not that that doesn't happen in the very first of examples, but in this they would join up, gang up and treat you like the dirt beneath their feet, except worse. All for trying something a bit different on a normal game and the such. And finally the "other' reasons. I don't really have a better word for this. Simply put, I'll give one example. I highlighted Soraka, intending to play that as a support, a meta pick which was also very strong at the time i intended to play her. Our top laner proceeded to ban her after seeing me highlight her. I remember how i started with the phrase, "Dude, i wanted to play her. Why did you ban her?'. His simple answer was "I don't like soraka" or "I hate soraka", i can't quite recall if it was like or hate but otherwise that was his precise statement. Any attempts at reasoning were ignored, he just laughed and insulted me for being a ''garbage'' player that would play the champion he didn't happen to like, the team not giving a damn or even stirring him on or joining in on his fun. There are hostile and quite, let's say dis-likable players to say it in the least, and dealing with them isn't going to be a snap of the fingers. Monitoring the champion select doesn't seem like it'll be something focused on any time soon either and even if it was it would only work to punish this griefing, which isn't honestly the solution I personally would go after. I think we need a simple method to just deny this possibility. And there's a relatively simple one indeed. At least by my understanding. Being to highlight champs is a very nice feature, it works with communication, helps in bans and is an overall boon that helps the pace at which champion select proceeds by a large margin, however, it also more so enables the banning of allied champions as you can clear as day see what they want and react fast and ruin their game in an instant. Simply put, I believe it would be best if "highlighting" a champion in the pre-ban phase should make it so they can't be banned. That way if you select this or that champion, no "ally" can abuse it to instantly ban what you want for any of the above reasons or whatever the scallywag they can think up of for their own sadistic pleasures. It'll just gray out said champion and make it impossible for allies to proceed with such griefing. Yes, if someone were to miss-click or anything of the sort, that could be an issue by them confusing the -pre-ban with the ban phase, but come on, if they're that distracted it's their fault. That's pretty much it. I think this is a very much overlooked problem that needs to be properly addressed as too many players end up AFK waiting 30 minutes to start a game, panic pick something or some other conundrum after someone screws them over for their own twisted sense of joy or just because they weren't fond of what they got as a pick. So. What do you think? Do you agree with this method? Do you have any idea how it can be better or a different one. Please do give your opinions. This should be dealt with and the only way Riot with accept an incentive for that and act is if we ourselves were to act and call out to them first.

P.S. - I decided that it might help to add a poll. Simply put, note if you believe that highlights should gray out champions and make it so they can't be banned or not. Would be interesting to say a more statistic feedback on said idea. Much obliged for your vote and opinion, thank you for your support.

EDIT: To avoid the dangers of miss-selecting the champion you want to ban and them being un-bannable, instead of making it so the highlighted champion can't be banned, it should make it so the highlighted champion can't be banned by anyone other than you, fixing the only real problem that could arise from this idea. Thank you for noting my oversight DuskDaUmbreon.

EDIT: A lot of people have been noting two problems that could arise from that so let's look over them in order. 1 - Highlighting someone people want to be banned so said champion can't be banned as an attempt to grief your own team. This isn't really a problem since the highlight phase comes first and the ban one right after, making it impossible for them to read your mind and chose someone you want to ban unless you specifically wrote "ban ----" in chat which can be avoided by writing it and simply waiting to enter it exactly when the ban phase starts. 2 - A more prominent note is the usual considered overly strong champion picks. If an ally highlights one of the currently considered as overpowered champions, be it to pick them or so you can't ban because they have a desire to grief. In the second scenario, if they're really going that far, without any reason to grief anyone specific and just ruin it for the whole team, it seems like they'll do plenty enough in game to make this kind of action pale in comparison. In the first one though, while of course, there is no perfect way around it, it isn't impossible to deal with. For one, a champion can always be picked away from even your first pick if the enemy is "the" first pick of this select, not to mention that in all honestly, well over 30 or so champions deserve an equal title of scallywag overpowered, meaning that you'll never really be able to deal with them fully. To potentially avoid such threats of a champion you really don't like, we can go back on communication, or at least attempts on that. If the highlight phase is simply increased in duration from 15 to a not at all too long 30 seconds, you'll have time to tell them you really can't deal with this or that and so forth and they may swap their highlight or ban the champion themselves, even if it is a bit of wishful thinking it's not an impossibility. That being said, you also have the potential to counter pick if that champion happens to be selected, and obviously, if you happen to have an ally's champion, you can trade with them if you're a sooner pick, avoiding such dangers instead of forcing them out of picking a champion they're comfortable with. Since this worry is mainly focused on the overpowered champions, they're far too many to cover with 10 bans, regardless 5, and usually a lot of people tend to have them, which would mean you won't be able to deal with all of them on your ban phase and regardless still probably need to outright outplay or counter pick them. So yes, some attempts at communication, picking for allies, a number of solutions are available to better this problem.
