Grav/Dragons got nerfed, with a much smaller radius on Zarya’s Graviton.
I think Snipers are the biggest losers with these patch notes and Dive heroes the biggest winners.
Mercy can no longer outheal Winston, and both Hanzo and Widowmaker got the CD on their mobility options reduced (1s for Leap, 2s for Hook), making Diving them much easier.
Zarya got Graviton size reduced, which hurts the power of Grav/Dragons, especially with Mercy being unable to boost it to burn through Transcendence now.
Brig got her shield buff nerfed, solid enough indirect buff to Dive heroes.
Wrecking Ball will be introduced in Comp probably around the same time, a solid answer to Snipers.
Lucio’s buffs are pretty huge, and this will greatly benefit healers who rely on his synergy, like Moira and Ana.
Ana’s Nano-Boost makes it much safer on squishies and insanely powerful on Tanks, with it essentially being a Lay on Hands now.
Moira’s buffs don’t really mean anything. If she did nothing with her RMB, it changes it from taking 45 seconds to fully charge her LMB to 37.5. Not exactly gamebreaking.
The buffs on the current PTR will make Soldier, McCree and Mei far more attractive relative to Snipers.
Overall I think the changes on both the current PTR and the one that’s upcoming are steps in the right direction. Whether they’re enough to change the meta on their own is a different question, but at the bare minimum they’re closing the gaps between comps effectiveness, and we’ll see a significant dip in how good Double Sniper is, especially against Dive.
Also as a side-note, it’s gunna be sad days being a Pharah, with reduced Mercy healing AND a massively stronger McCree and Soldier.
