Guerilla should work from sneak OR "Shadow Walk". Hope that this skill will no require Surce point again.
If any skill requires a source point then Levitate, its incredibly strong, I would say it breaks the game.
The ShadowWalk is a sneak for combat. It has cool-down. And Ignores facing enemies. As long as DOS has no cost for turning, classic sneak cant work. Can you imagine a PvP fight where you turn around for free to find a rogue ? That is totally poison play. Current rules are so twisted already, do not add another nonsense.
