IMO: Titans, especially the Defender Sub-class, work well in team based matches or PvE. I mean a buddy and I steam rolled the entire enemy team one match. He's a Defender and I'm a Striker, backed up by a Bladedancer Hunter. Both Titan had auto-rifles and shottys, we get mobbed, the Defender pops his shield, and we switch to the shottys. If it gets too dicey either the Striker of the Bladedancer triggers their Super, and we keep rolling. All three of us had headsets, which made life pretty easy. TL;DR: Buddy up, Use Headset, Steamroll
