Can't have fun league anymore

Honestly I've been playing league long enough to know that in this meta, you have to play certain champions in order to win games, that primarily being tanks with cc and etc. I like playing adc or some fighter top but I would always end up winning lane but losing game cause their "team comp is better". For example, every time i play amumu jg i would always win games or if i go malphite, irelia, trundle, etc. I don't have fun playing them because they are basically farm and do nothing but qwer them, but thats just me. Either they are just really boring to play or theyre so strong as a champion that it makes the game too easy which also isn't fun. You can say that champions aren't op or broken but tbh there are champions that are just hard to play against no matter who or how you play, and I've played those kind of champions. Its not fun. I like adc because its the most difficult and mechanically demanding but if I'm going to lose because adc's are known to just get 1 shotted by everyone then thats not fun at all. Just get a team comp with peel and cc? I can try and ask but I don't think I have any place to tell them who to play cause most of the time, they too will play someone they have fun with.

The end of my rant.
