shift key + basic attack spam on katari is great way to wipe the map of annoying spearmen and sarabas, just beware of the pink slosh she chucks on the floor all around her because no matter how much killing you do you die to the invisible tick.... of course the fact they totally ignore any defense on your toon and hit like your in paper armour doesn't help things at all either, bioware broke something when they added the two new faction into the game, instead of utilising existing defence mechanics they adjusted the values to make them harder and now more games wipe than succeed against them even on the easier difficulties, its one of the main reasons why faction selector should have been added, I romp through peri against the original factions but often find ds/Qun a problem, on nightmare I can hold my own against the original 3 factions but against ds/Qun I get obliterated every time /
the quanri defenders are stupid because theres so many of them and they block everything unless you hit them from behind and even then they lie on the floor dead for 5 minutes waiting for someone to come close enough to kill with the detonation ......
which makes them a chore to play against, most of the time if i'm solo I will just quit the game as soon as I see its them rather than struggle against them and get annoyed at their cheapeness, bioware clearly didn't learn anything from adding the collector faction to me3mp after release and should have coded them in from the start....
