[@Flamelord] They have low life force you say? 

Have you perhaps met ... [url=https://www.youtube.com/watch?v=GOGq39FBZEY]The Gatekeeper[/url]?

Them super Kull zombies. 

More seriously, the fact that they have a short life does seem like a glaring weakness toward energy sapping foes like this. Ba'al better prepare them snipers.

Energy sapping foes don't exist like that in Stargate. The Kull are terminators designed to carry out a mission, disregarding all obstacles, and then once they're done they have served their purpose. Ba'al is working on making them live longer, but as it stands their body is just too good for the functions needed to sustain their life to keep up with. 

Once he realizes that the Dark Outliners have abilities akin to the Ancients, he'll probably work to fix that.
