Any plans to tweak this mode in higher level void crusade missions? Changing the extraction ability ('5' hotkey) to lock on to the target once you begin its extraction would help immensely. As it is now, you have to start from scratch every time the target moves a bit.
While doing a mission 8 levels above mine, I rushed to the target, and attempted its extraction five times - only for the target to move slightly each time (usually as the progress bar was about to reach max) and then failed the mission as all the mobs overran me.
Changing the target behaviour to get stunned when you begin its extraction or simply enabling a lock on mechanics in case the target moves (within a reasonable area, of course) would help this mode a lot.
