Overwatch · Low Tier
A damage boost that decays is meant to stop Mercy players from pocketing a single player and push them to spread the boost across the whole team.
For each hero in D and F tier, slightly buff each part of the kit. Not every suggestion needs to be implemented, but all of them should be taken into consideration.
Each entry lists the move or ability affected, the adjustment itself, and — where the analysis states one — the problem it is meant to solve and the reasoning behind it.
Mercy is one of Overwatch's entries — the full tier-by-tier breakdown covers the whole roster.
