I understand what you mean, but i still disagree with how you balance certain champs. Its a hamfisted way to balance a game which has random team comps and skill lvls. Assasins are super unfun to play against just as much as being poked at range is unfun. But just uber buffing assasins so they can one shot anything in their sight with less risk isnt any better.
I think Assassins with huge damage buffs are unfun to play against, but they certainly aren't powerful without them. We did an analysis of the roster, comparing their ARAM win rate and what we believe the win rate would be without the mods by assigning win rate values to 1% of each mod and then back calculating. In ARAM, assassins had something like a 40% AVERAGE win rate if we didn't have any mods on. The goal here is to find ways of making playing them not garbage but not have to give them tools like "one QE kills half their team"
