A little change to Mercy's kit.

I think it would be much better if Mercy couldn't fly to her teammates' dead bodies. That way, before resurrecting, you'd have to think about what you're doing and hide or run away. Instead, right now, Mercy can just dash 50 meters in under one second (with her hitbox being much smaller) and resurrect her whole team which often results in the better team losing just because they didn't manage to instantly kill flying Mercy.
