I kinda like that the main heros have a bit lower stats compared to heros of the same color, talking not about command strength and intelligence but rather the crit dodge and block. I mean afterall they are free, they should be weaker than the "heros of legend" at the start. But as the game goes on and they grow they should be able to take their place and stand among the heros of legend, which by the way all have distinguishing skills. I just would like the main heros to end up with access to a skill that wasn't the same as the basic units.
