Agreed. If dealt with correctly, most Marauder's drop like a stone. I, myself, have seen it - you get surrounded on Voidstar or Huttball by 2 or 3 players who know what they're doing, you'll drop quicker than a boulder. Hell, even if they are OP'd, someone playing a Marauder who either A) Doesn't know how to play the class correctly or B) Isn't paying attention, can easily be stamped out in a few seconds.
Least that's my experiences, both having played against and playing as a Marauder.
