Start doing some katta faction and gear out all your toons with praetorians at ally( 1200 faction from start to finish, orux/2=faction or single tasks are generally 10 faction per) really nice gear(I think about the best groupable possible?) figure doing a 25 orux task will take you 96 missions to get your group to ally and if you find less used tasks(like I did one last night that gave 67 and took us 90min to finish but we were learning)you can get alot more orux which also breaks down to alot more faction.
