I'm up for killing any world boss you guys want to target. Just name a time and a place on a weekend date (since I'm mostly unavailable on weekdays) and I can tank with my Vanguard for you guys. Alternatively, it may be possible to get Mav to use his Jedi Shadow, Kage (lol get it?) to Tank for you if you can't find me around.
As for a list of possible targets... here you go:
Note that on the Imperial side I'm rolling a Sith Marauder so I can't tank on that side. For now, I'm only available to tank on the Republic side only.
