I've done the exotic sword strike another two times today. EVERY TIME I get to the wardens, somebody either kills alak-hul first, or they kill heolstor (and their wardens) way too soon. I've done it around six times now, and each time my team members have screwed me over, since I'm trying to get Dark-Drinker. It's so frustrating. I actually rage quit the whole game for several months after the first four times or so. At this rate, I'll never get it. I really like this game, but this is breaking my will to play it. If anybody on the Ps3 is willing to help, I would greatly appreciate it.
