I don't feel like there are good enough abilities that I would want to use this. I am sure this will rapidly change as more units get added to the roster. Perhaps that caster unit with [[Galavax]] is good.
Some of the hotkeys on mercs are kind of bad, which is understandable given the sheer amount of variety. Perhaps I am also downplaying some of them, and tweaking the hotkeys will make them more friendly.

I would ignore this for now, unless there is a very powerful caster unit added to the game. Like anything with summons via energy spending and cooldowns.
