Jungle Assassins and Tanks
I feel like Riot has inverted S4 situation: everyone picked assassins and tanks were considered unviable (although I had 78% winrate with Nautilus jungle on over 50 games); now everyone uses tanks and assassins are really not good to climb with. That is not what strategic diversity looks like, that is just inverting the situation. Inverting overpowered with underpowered does not make for a better environment. Same thing happening, just the opposite. I really hope they focus a little bit more on solving this, because I really don't think the jungle is in a good state.
and many more waht i cba to list. Theese are even pretty fotm champions for long period of time in yoloq.
