Want to get past HK-47 in foundry? Dont be bad. CC the first two droids that come out and right off the bat burn hk down and only focus on him. The adds hit like wet noodles(you) so you dont have to worry about that trash. Just blow all your cooldowns and burn the boss. If he does bug in the center and has his buff on that makes him **** have the tank face him away from the group and pop cooldowns. At that point you continue to nuke his face down. Its not hard. He dies quick. If you fail on HK I would love to see you on Revan before the patch. That was a FUN fight. Too bad we downed him on a regular basis without problems.
