So recently I started a new colony with a Bladedancer. First skill I got was Phase Strike and set it on auto-cast. Since he was my hauler, he got to use the skill a lot for making trips faster.

Thing is, all I did was spec all into -% cost for casting and +stamina regen so he could use it more often whenever he leveled up. Still, I find it a bit unbalanced that he got to level 136 so fast and became a god among men and destroys ranged raids single-handed in melee.

My suggestion would be to significantly lower the XP Phase Skip gives with each use, but keep the auto-cast feature (because that is really really useful for speeding up labor). On top of that, adding the auto-cast in similar skills like the Monk's Dragon Strike (even though you can't target the ground with it) would be marvelous.
