Agreed, Guerilla is now too poor of a talent to be worth picking.
Mortal Blow never seemed a problem to me because it was so darned inconvenient, only worked with the weakest melee weapon, and required a source point. If you aren't in combat yet it's a nightmare trying to Mortal Blow a moving target with a Backstab. I often would get sighted during the animation of the skill and it wouldn't even give me the 500% bonus.
Snipe on the other hand is really useful. It was easy to pre-buff (Rage and Flesh Sacrifice) and 1-shot enemies before a fight, especially with the old 50% Guerilla talent. Snipe is now even stronger as an opener when using a Crossbow.
