In raw HP but winstons cooldown is longer, Orisa does more damage, has way more armor, has fortify, etc. but Winston is more mobile and that’s the trade off. Comparing one stat is useless without looking at The whole picture.
I mean im sure the casuals are winning already getting free SR on orisa/sigma/moira it does not take skill to play tank right now tanks decide how the game goes right now.
Tanks are been moved to the spot they are supposed to be in to make space for their dps to land kills not deny half of the map with shiny barriers and go for a toilet break while the enemy hitscans are trying to break your shield.
Its not 50% its 70 per body shot instead of 80 he can still melt through armor fast with a headshot.
its 7 damage per pellet x 20 for 1 shot old armor took 3 damage away per pellet if it was over 6 damage so 4x20=80
New armor halfs damage if it is under 10 so its now 3.5 damage reduced per pellet 3.5x20 so body shots are not really nerfed but the headshots is where it starts to get pretty bad reaper now does 180 damage pointblank to the head instead of 220.
