So my Set is 3 Set Striker because its bugged and because the Talent Obliterate is better right now because its not punishing as Striker. (3 Set Striker 1x Sombra Chest (+15% Crit) 2 Set SMG Set (10% SMG and 15% Crit)
So what does it do. Every Crit increase the Weapon Damage by 1% stacks up to 15. That means +15% Weapon Damage. I use most of the Time the Vector or The Banshee.
So The Banshee 95.4k DPB and with a full Talent Buff +15% more Damage is the Weapon Damage the same 95.4k Damage and it doesn´t feel its working.
Check the DPB with no Buff and with Full Buff all the same DPB. Mostly u need one clip to get full Chest Talent Buff. There is a symbol right under ur HUD where also the Striker 4 Set Bonus is. If the Bar is full that means u have the full 15% Damage Buff.
Its like the Same I have 4 Item with full 15% Weapon Damage if I remove one Item the DPB Damage goes down like it should be.
