Oooh let me try…
All role passives removed, DPS passive is given to every hero but is reduced to 10% (can stack to 20%) I’m keeping this because I don’t want to nerf healing. I’m also keeping the self healing passive
Dva: max hp reduced to 550 DM duration reduced to 2 seconds
Doomfist: max hp reduced to 400, block damage reduction reduced to 50%, overhealth gain reduced to 30 - To a max of 100.
Sigma: max hp reduced to 400, kinetic grasp no longer grants overhealth.
Ball: max hp reduced to 450, shield can no longer be shared with teammates adaptive shield gain reduced to 100 per enemy.
Junkerqueen: max health reduced to 375, shout no longer grants overhealth to allies, overhealth gain reduced to 125, cooldown reduced to 8 seconds, passive bleed healing reverted to 2x bleed damage done.
Mauga: no longer has armour, max hp reduced to 500, overdrive no longer effects teammates damage reduction reduced to 30% lifesteal reduced to 30% ignition threshold for the incendiary chaingun, changed to be 25% of the targets max hp.
Rein: shield hp reduced to 1200, no longer has two fire strikes, max hp reduced to 550.
Winston: max hp reduced to 500.
Orisa: max hp reduced to 400, fortify no longer grants overhealth or makes her immune to headshots and damage reduction is reduced to 30%
Zarya: max hp reduced to 400, has one bubble for herself and one for a teammate.
Rammatra: max hp in omnic form reduced to 375, armour gain from nemesis form reduced to 125
Hog: max hp reduced to 600, TAB healing reduced to 300 damage reduction removed, resource regen rate decreased by 20%, can no longer use hook or TAB while ulting.
I will just mention some support changes as well, brig: inspire no longer follows brig it’s radius will be reduced to 6m.
Bap: regen burst no longer heals for more below 50% hp and is reduced to a 100hp burst, immortality is no longer an aoe deployable but is instead single target with 3 charges, it will no longer prevent death but will instead negate one instance of damage before breaking and the effect will last 3 seconds (think of it like a bubble with only 1hp it can stop any amount of damage but breaks instantly)
I mention these two supports because these are the supports that ruined 6v6 in the first place by enabling goats and double shield.
