<— 4.1k Mei main, currently around #50 Mei in the world, with around 250 Mei hours across all modes

Mei spraying the floor to increase her movement speed does not address her weaknesses, which are:

Her slow ultimate cast time

Her ultimate’s inability to freeze people

Personally I’d like to see Mei’s ultimate cast reworked to be more like Tracer’s, where the projectile leaves her hand almost immediately after the button press.

Mei’s ultimate is weak because without the assistance of her primary fire, it takes 3 seconds to freeze targets. 3 seconds in Overwatch is an eternity, and thus her ultimate is ridiculously easy to escape. The change I’d like to see would be for her ultimate to take 2 seconds to freeze.

The previous buff Mei received to her primary fire more or less solved the problem of heroes like Tracer being impossible to freeze, so that part of her kit is now fine.
