I see that one of the weekly challenges involves killing only 30 of these things for 20k exp. If I wanted to try one of the missions and just rush through on the easiest difficulty to kill them all quickly, which would be the best? In other words, which has the most knights the soonest?
Now how about jackals? I figure any ol' mission would do fine for those, but is there any one in particular that's just dense with them? Also, do I need to do these in matchmaking, or can I just start a mission by myself?
