What people (including my selfe) makes raging about Zed is not his assassasination potenzial. It's this super obnoxious Laningphase! The Ults panic button is just a high point.
The problem with Rangar starts with them same problems of other Assassins. In late game you either Counter-Build them (Which is BS) or you die! There is 0 Skill included whem playing against those Champs!
Rengar is a little special case because he just ignores the stuff you're trying. I'm Diamond - the League where you could expect an atleast OK Skill-Level. And yet... people dying with all their Abilities and Items UP.
The avarage reaction time is something about 200ms... 200ms is the time rengar needs to kill you. Including ping and delays... you cant do shit! And this make people really mad. Where is the point of playing, when you get greyscreened with zhonyas in your inventory.
That's not chess (I love chess - but this is League!) where you trade just figures. 'Take our ADC we Take your Rengo' Said ADC may wants to play this game as well? With a decent amount of action and reaction?
These whole Assassin class... they are just the counter to fun in this game for everyone who does not play them. And they are META, should a supposly High-Risk class really be the most effective tactic aviable? I dont think so - still Riot does everything they can to buff them back to Meta the second they're in danger to fall out... pathetic.
In League this whole High-Risk High-Reward got dumpstered. Immobile Champs are High Risk now. Mobility Champs are the standard. Thats so NOT good!
