168, a lot of time for the summer and just wasting it on vidya gaems. If it means anything, I have only played 4 soloq games for the entirety of playing this game.
As far as the tickrate goes, I'm sure it'll improve overtime. I mean people are still crying for 128t servers in csgo because Valve MM servers are 64. About 90% of the player base wouldn't even know the real difference.. just a buzzword tbh. The hitboxes are fine and i'd be surprised if they even tried to "fix" it. Sure some games reward for fine placed aim, and so does this.. it just so happens that you have targets that move with dashes, wall climbs, and fly all around the place. No matter the case, its not "random" you just happen to be larger than you appear. Getting hit behind a wall like that is actually extremely rare. Out of all the games i've played and watched deathcams.. I have only noticed it happen once or twice but doing it deliberately is even harder.
It's fair to say it does lower the skill ceiling a little bit when it comes to hitting heads, but it won't change the fact someone is better than you and/or can out aim you regardless of the situation. Lets be real, when has blizzard take a game genre and make it general/casual/easy for the masses?
