The Mercy sucks to use. It has trouble landing because its turn radius sucks, it handles like a blimp, and it doesn't even recharge fuel when landing.
All of these things should be fixed. If the stupid thing has to be fragile, then it shouldn't handle like a Soul Ripper.
Please don't, it'll turn Seton's into a boring snipefest.
Rather fix Blazes not following orders - now THAT is annoying.
