To be specific, all of the options available plus one more.
Above all else....
EVERYONE TRY HARDS..... IN EVERYTHING!
In norms people abuse the most broken champs possible, flame and threaten to report you when you do something different (vel, braum, bard jg) and your opponents continue to kill you at every opportunity just to rub in the fact that "they win and you don't". How good does it feel for top laner X when top laner Y dives and kills you whenever their ult comes off CD until they don't need it anymore. You may say I'm bad, but that's what happens when you go braum top for a lil fun, only to go up against a darius/riven. There's nothing to be done but die, over and over.
Look at rotating game modes. In the beginning, we were all hyped for urf and one for all. We all probably tried stupid/absurd stuff like donger, karthus, naut, rek sai, bard and my god the list goes on, just to have a laugh cos they were still so stupid in theory because the modes were still new and we'd never tried it before. It was awesome, it was fun.
Now when urf comes around, it's riven, zed, kat, nid and some other broken pick. And they power down, wreck you and end the game asap. It's not about having a good game anymore for so many people, it's about winning and getting that S rank, or looking good in front of your team. They don't care about seeing dumb stuff happen, they care about making you see a grey screen for as long as possible.
Then one for all; blitz, riven, Darius, Annie ect. Mean while me and my buds picked bard or naut and proceed to get stomped in 10 minutes. Fun right?
It's the same in every featured game mode, people don't value to time they have with it, because it'll be back in a matter of weeks. So they treat it like norms and try and trample everyone in their path.
The cause of all this? Riots changes have made it a stomp or be stomped game. NO ONE WANTS TO BE STOMPED. So they try as hard as possible to be the brats doing the stomping. How often do you see people trying to break the meta? How often do they do a kill lane bot or a themed team composition?
I haven't versed any of those in over a year, hell it's probably longer than that, maybe even over 2 years. I've played with some because well, my friends liked doing dumb stuff. (One for all doesn't count as a theme btw)
The only people I saw doing off meta stuff, are my buds because they despised abusing FOTM and god tier picks. One mained lulu/raka adc, another ad/ap janna mid+top, another AD elise jungle just for a little picture. And I just filled in where I was needed when I played with them, spamming the random champion button until it auto locked me in. Best times were, when we faced another 5man doing something as dumb as our own. But that was years ago, back when kass reigned supreme and tanks were tanks, fighters were fighters. Not bloody burst mages with 5000 hp, tank assassins or hyper mobile juggernauts.
But now they're gone, they quit because they couldn't play the way they wanted to and enjoy it, because when they did they'd go up against try hards that'd stomp their goofy champion pool beneath their dirty little feet. They'd get salty, and ff at 20 because it was the same dam thing every dam game.
We tried aram, but with so many accounts made specifically for aram with only the champions they want, we couldn't escape there either, because we all own nearly every champion, only to get say...... urgot, jhin, sejuani, yorick and singed and go up against a lux, annie, cait, raka and yasuo.
And don't bother telling me "Well it's your own fault for picking those champions", I should be able to pick any champion into any position and expect a reasonable experience. I shouldn't have to drop down to try hard mode just to have a half decent experience where I don't get stomped.
Well that sums me up. [zombie-brand-clap]
