As stated in title, after playing a mercenary and marauder, who both have "stacks" they have to spec into a utility to pre-stack for a fight, i noticed ap powertechs have their stacks (energy lode) baked-in to their talents, freeing up a utility point. Seems like such a minor thing, but wondering why only powertechs have something like this baked-in to their talent tree, and why the other classes have to waste a utility point to get it.
