Why do people say Riven is hard?

I mean ...

3 second 500 hp shield that makes your dumb moves basically unpunishable, 2 aoe stuns and an aoe execute ultimate ability that literally requires no brain to use ?

Let's not forget the fact that Riven's power level is actually ABOVE her intended power level due to animation cancelling glitches in her kit.

I think we all forgot how broken and easy this champion is. She can 1 shot any tank early game, and then just lifesteal all their damage late game.

Late game CCing her doesn't work either, she will always have her E up and use it to dash to a more favourable position while soaking a lot of the cc damage and then either fly away or jump back onto your team.

I don't know how Riot still didn't nerf (FIX THE BUGS) on this champion.

Are they afraid of all the weebs being mad or something? Like they were with Lee sin ?

Let's also not forget the fact that she has no counters in the game, she can "outplay" all of them with either her insane damage or the shield that scales with AD and makes Shen look like a squishy
