Its been a while since anyone complained about this ..soo..

Currently the number of bots per bonus is based on the highest leveled player * group members and the bonus is the same as going solo. As soon as any member has even slightly higher levels than the rest grouping becomes pointless.
At my level I have to blow up 11 bots to get a bonus.

I've suggested to some "newbie" to go group botting with me but it'd have probably taken more than twice as long to get any combat xp as when he went solo.

I'd suggest basing the number of bots on the average level of the members or scaling the reward with the number of members (although I prefer many small rewards over few large ones).

also ... the mission status display is kinda borked when grouped

If the devs take some time to tweak the inner workings of this mission, it would be great if they could also fix the <hudtext></hudtext> issue.
