To be honest, I don't think Sneak+Guerrilla deserved the nerf in the first place. Sure it was an extra 50% damage, but it's far from the only 50% damage you can get. For the cost of 1 talent, 15 skill points (or gear equivalent), 1 extra AP per attack, and maneuvering in battle to avoid sight cones, that was a 50% well earned.
If they had nerfed all the other damage boosts and made that kind of high damage very hard to come by I could understand the nerf. As it is, I can still use bully, power stance, and rage (works for rangers too!), knockdown my enemy and crit for 1500. I just finished my tactition mode playthrough and the only boss that even managed to take its turn past act 1 was Leandra and only because I was forced to wait out her Void Aura. All three of those modifiers are cheaper than Guerrilla ever was.
