Both of Mei changes could go through I suppose. The one with the beam increasing the movement speed should also apply to her team and with more increased speed than in that exc. The ice block makes sense after all, nobody in real life would live if a block of ice landed on them lol. Or most likely they’d be in critical health condition.
Although they are not so amazing compared to what others got, it’d be a good start to make her more helpful / less clunkier
I personally would give her 50 extra shields or less cd on wall / cryo before any of these
