What do you classify as Inting?
TIme goes by, but things remain the same in League. Same mistakes happen, people are still indifferent to knowing good build paths or skill maxing order or runes etc, which means that they are not doing the maximum of what their character can do.
With this in mind, what do you people recognise as Intentional feeding or bad plays in general? For me, it's a lot of things. For one, it's the obvious "running down mid". But moving away from trolls, let's talk about real things.
Personally, I can't stand when people play a champion with bad runes, bad items etc. I just can't. For example, with the new runes update, I had some friends who were "bored" to read through the changes so they just picked whatever seemed close to the old ways and went with that. To me, that should be punishable. You are intentionally taking on a non-optimal rune, thus putting behind yourself and therefore the team. Same goes for itemization. People are "bored" to read what this new item does or if it fits the playstle of their champion or the team. For example, a Locket is a VERY USEFUL item when it comes to teamfighting, to the point that if one team has it and the other doesn't, then the team what does not will probably lose the fight. Therefore, building a Locket somewhere down the line is almost mandatory, especially if you have an appropriate champion to do so (tanks / supports). So, not building one as a Taric support should be punishable. It's such a good item what can win you a game. I can compare it to something like not using your Orianna R to set up a good fight.
Same can be said about Summoner Spells (lack of an Exhaust vs an assassin), skill order etc. There is almost no reason to max E on Sivir for example, and doing so is probably gonna lose you the lane and probably even the game.
The funny thing about all these is that it's not mechanical skill. It doesn't require you to have fast fingers, precise clicking or fast reactions. It doesn't need you to be able to have the game sense to predict or whatever else. It's just basic game knowledge that EVERYONE can and should have. And I'm not talking about spending hours on end on wiki and probuilds and pro streamers to see what's best (even though it's a really good way), no, I'm talking about getting to know basic stuff. Just like how important Locket is for example. Things that do not take a lot of time or effort or skill to implement in your game, but they make a huge difference. Instead of practicing for perfect CSing 5 hours a day, it would probably be better to know what is the best itemization you can have, best rune setup etc.
I guess what I'm trying to say is that knowledge is power, and in 2018, not having knowledge is not acceptable. There are way too much sources where you can get knowledge for the game, even just basic stuff if you don't really wanna dive into it. I don't know if lack of knowledge should be punishable or not, but what I DO know is that you can't really complain about the guy who didn't use his ultimate in a fight or didn't use his flash or didn't land a skillshot, when you yourself didn't do your own part to help your team the best way possible.
There is the "active" part of helping your team (mechanics, game sense etc) and then there is the passive (game knowledge). You can't be an "active god", but you can gain knowledge. Get your "passive" skills high because you can, and worry about "active" skills later on, because you might not be able to get better on them. Get your baseline to where it should be.
