We seriously need to talk about hitbox powercreep
At this point it's getting ridiculous how real hitbox powercreep is. The biggest hitboxes almost exclusively belong to older characters. Just from the beginning of this year we've had only skinny characters. Domina is the only immobile big hitbox hero we've had and she's a tank.
Anran - Tracer sized, fast, jumps high, ridiculous mobility, invulnerability, throws up VFX
Cat - tiny, flying, fast (probably the easiest to hit from this list)
Mizuki - also skinny and fast
Emre - probably the biggest hitbox we've had on a DPS and he's only Soldier sized
Sierra - absolutely ridiculous size hitbox, with her bobble when strafing, just disgustingly hard to hit
Shion - larger than the previous ones but not nearly the size of something like Echo, has a million mobility cooldowns, overhealth, etc.
Let's go back now:
Vendetta - skinny hitbox, fast as shit, flying through the air half the time, breaking her spine on every hit, looks like inflatable tube man when attacking (and has the hitbox to show for it)
Wuyang - also really small hitbox and fast as hell
Freja - here things weren't so annoying so she has a bit bigger hitbox
Other older ones like Juno and Illari, KIRIKO (who keeps her damn hand in front of her face) are notoriously hard to hit as well. Not one of these characters has even come closer to 200hp, and size/mobility/health relation doesn't seem to be a factor in Blizzard's design philosophy anymore (looking at you Anran).
The new support will also likely be a stick-inspired omnic with 10 kinds of mobility who wobbles around when attacking. At some point the game is going to be so saturated that not playing a skinny asian girl will be akin to throwing.
