Don't know why the tw.battle.net forums broke it first, but at least on PC two of the deadliest heroes get a balancing nerf.
Brief translation:
McCree
- Alternate fire
- Damage decrease from 70 to 45
- Time before reloading decrease from 0.75 seconds to 0.3 seconds (Probably reverse patch form this)
- Damage decrease from 70 to 45
- Alternate fire
WidowMaker
- Alternate fire (Snipe)
- Base damage decrease from 15 to 12 (damage multiplier from charging doesn't change)
- Headshot damage multiplier increase from x2 to x2.5
- Player can only re-enter "sniping mode" after the "exit snipe mode" animation finish
- Infra-Sight (Ult)
- Ultimate charge cost increased by 10%
- Alternate fire (Snipe)
Bug Fixed
- Improve custom game "High bandwidth Mode" stability
- Mercy will no longer charge her ult if her right click target is shooting shield or ice wall
- Reaper will no longer teleport to weird places
- Fix some bugs in Dorado (Should include the Symmetra one)
Translation via u/Summon528 on Reddit.
What this essentially means is that McCree will no longer be able to shred tanks with his Fan the Hammer, especially when he rolls to reload and hit it again. Widowmaker will still be lethal but the emphasis will be on finesse rather than landing a body shot. This increases survivability of low HP heroes like Tracer and Zenyatta who get decimated with body shots. Her headshot damage is unchanged.
personally, I welcome the change and see this as a positive push forward to balance such a widely popular game.
