Do simple champion kits inspire salt/frustration/toxicity?

Personally I can't stand losing a lane,duel, etc. to a champion that basically has like -1 ability they actually need to think about before usin. Ex. Yi or fizz you get the picture. I can't (I'm trying to pick up azir in the assassin meta of all fucking things) imagine a player taking the time to Learn the Inn's and outs of Lee Sin, Azir, GP, and getting beaten because (insert champion) just kind of has to right click you and push (x) when needed. Like I get that there need to be entry level champions, and some people enjoy that simplicity, but it makes players that have put time and effort into say learning Riven's mechanics (no i dont play her) and then just kind of getting fucked because early game Garen.

Imagine learning Yasuo, and then getting smashed by a yi player because he just kind of counters you. All he needs to do is q or avoid your trnado and you lose/or kill you before you can stack it. Which is fine, but not exactly thrilling for the opposing end. Idk. Obviously there aint a fix for this, but i imagine not everyone is pleased getting "outplayed" by a tryndamere of all things as Rumble because he pressed r and ou basically have to kite or die. And you better not miss your E ;)

Anyone else? Just felt like talkin about that. I generally just get annoyed
