Pretty good on heat if you make sure to keep an eye on it and basically max armor. Fast enough to hang near lights but tanky enough to help out heavies and assaults. I've managed some decent damage with it overall and a couple of 700+. Buddy of mine that I introduced to MWO built this his second week playing and is tearing Tier 5 a new one. I built it after seeing a couple of his games and it is so much fun.
