when comparing units you should be using average stat increases not the level ups you have had in your playthrough, giving characters a 5% buff or nerf changes almost nothing, (that's one stat point per 20 level ups), giving Kate 12 con isn't a good idea from a non-gameplay standpoint, as she would be larger than characters like Marcus. if you believe there should be actual changes, then you should suggest changes to bases. However, for the most part I feel like SOA is very well balanced, I'm certain that they have taken into account many aspects of balancing, and they will take care of necessary changes. (not trying to be rude just pointing out my disagreements with your suggestions)
