I find this topic interesting and am thinking I will try Baardvark's mod (thanks for creating it, sir!), probably using the DnD version. I'm wondering though, if this won't make Constitution a more important attribute?
If I correctly understand Baardvark's comments (https://www.nexusmods.com/divinityoriginalsin2/mods/58/?), the DnD version reduces the increase in vitality to 4+4% on level up, and since armor and damage values are based on this, they get reduced, as well. But I also understand that a point of constitution gives builds a 7% increase to health. So, am I right in believing this makes a point in constitution far more valuable than it was before?
