Okay, that's what I've experienced then. I recommend all Defenders in the Crucible run AoL, plus Force Barrier melee. I had one survive three arc blade strikes, then kill me with melee, allowing him to run out with the overshield and kill two more. Now when I see a purple bubble I run. I tried going in again last night because there was another of my team inside and I thought I could use Arc Blade to great effect; I killed the Titan but not before he killed both the teammate and then me at the same time as my last strike. Bladedancers who feel more confident getting in there are welcome to do it, I will be staying away. Easier targets are everywhere.
