Not quite, I'm an assassin player.
There's protect the adc meta (awful for assassisns), but still playable.
Enchanters meta (awful for assassins), but still playable.
Control mages mid (awful for ap assassins, great for ad ones).
There's even the gank lv1-2 meta where it sucks to play as any lane (hi hi twich/ezreal jungle here i've come to ruin your day).
There's bruiser meta (like when darius and morde got reworked).
etc.
But out of all those.
Tank meta is the most utterly broken piece of shit this game ever had.
You either have assassins building tank and being better than bruisers (due to mobility) and close to impossible to kill (hi hi tank akali/ekko here, do you miss me?) or you have tanks that just run you over, like a bulldozer, and there's nothing you can do. As they will be to tanky to kill and they will kill you.
What's the benefits of current meta over a tank meta?
Well, even if someone got ahead like they killed their lane opponent 10 times in 11 minutes. If they misplay, if they misposition, if they don't pay attention or simply put, when they make mistakes, you can punish that and kill them.
This won't happen in the tank meta. When the tank meta gets rolling, there's no stopping. Yes, you won't lose in 15-18 minutes by all enemy lanes stomping and being able to take down structures like it can happen right now if everyone in the enemy team hard wins.
But you also, the team that's behind, it will lose. Its just a matter of time.
