I alerted a Renegar, Lazuli Titan today and gave it a saboteur/dark void combo. Knocked down about 94%. Second player jumped in and took it down to 125 hull points. At this stage we both backed off and let the only other eligible legionmate make the kill shot. When he did, I got a drop, player 2 got a drop, player 3 (disabler) got nothing (not even xp). Is this a glitch or is there a minimum amount of damage required to get a drop?
