supple palm
Based on my limited knowledge of Mei, she can be both a good defensive option, as well as having the ability to punish the enemy. The main thing is that wall imo, as it can be used to block off incoming damage as well as separating the enemy team if one overextends, like that Rein did a couple of times in the second vod. I would say the main things to work on is that wall utility and managing your cooldowns. Overall pretty good and would definitely have annoyed me as a Rein main.
