Is Flax so strong on Jebus Cross?
Actually, the differences in rules for individual templates are separate from the General ones, so there won't be any clutter.
He's not the weakest, so start strengthening the weak ones or weakening the strong ones. By strengthening the mid-tier factions, the gap between the weaker ones increases.
The fact that differences for templates are separate from the General ones is certainly more convenient to perceive, but still, the more exceptions there are, the worse it is.
