I have always been a Titan and am annoyed if I don't get top score. U have to be a striker which gives u a lot more fire power against your opponent. Defender is useless unless you are playing as a full on clan. U need to use the titans strengths or u will just fail. Run about with ur shoulder charge ready to stop shotgun boys. Use lightning pulse grenades but fire them at the walls not the floor. And make sure you have your extra lift on. Titans don't seem to be able to jump as high. It's what works for me every bodies different. I also find control is the best pvp for titans too.
