Cure Wounds is a trash skill after level 10 to 15, why? Because you don't even need it as a warrior for survivability, by that time you could easily achieve 100%+ in the four magic resistances. You'll heal up so much from enemy elemental attacks, physical and tenebrium attacks become almost meaningless with the resistance healing and also leech, which is more effective for front line units since they can tank easily with 6+ enemies surrounding them.
Those levels are actually when I started using cure wounds. My "paladin" and my friend's rogue are taking massive physical damage that simply has to be healed back quickly sometimes. Sure the much lower cooldown hydro regenerate would heal a decent chunk, but sometimes I take more damage than that in a single turn even with 100+ resistances, ~110 armor rating, and 44% block.
There's also some bug that causes cure wounds to heal the next turn as well, but I haven't figured out how to reproduce it yet, just had it happen a couple of times.
