Overwatch · High Tier
Echo is efficient at prioritizing a specific target with her abilities and at approaching that target quickly with her flight, so both come down a little.
For each hero in S and A tier, slightly nerf each part of the kit. The author notes these are not all meant to be implemented, and invites feedback on which should take priority.
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.
Echo is one of Overwatch's entries — the full tier-by-tier breakdown covers the whole roster.
