I often have trouble identifying who the VIP even is. By being an Atlas he is rather indistinct from virtually everyone else. The VIP indicator is only visible if directly staring at him, there isn't really an indication telling me "the VIP is WAY OVER THERE" or how to even find him as a defender.
Now, if the VIP were say an
Ambassador, a truly unique and reasonably quick mech with no weapons... then we'd be talking. Can't mistake that mech as anything else. Though my preference would be a tank. The
Behemoth seems fitting. The armor variant sports 4 LRM-5s on the tank and 2 AC/10s on the turret, and more armor than any 100 ton mech can actually carry. It also goes about as fast as MWO's VIP does. And at least it can also defend itself without having to actually "fight."
