overwatch tip

Mei's wall is great for assisting Mercy with rezzes.

It's probably common sense to most, but I've been seeing some Mei's in my games paying close attention to our Mercy and providing walls for her when she needs to rez.It's great to see this, especially since nobody has been asking them to do it. So just a friendly tip for anyone who likes playing Mei, take care of your Mercy, get more out of your rezzes :)
