many enhancing magic spells cap off at a certain point currently the only reason we have to even worry about our enhancing magic is for the new "gain" spells. examples

Tier one weapon enhancement magic stops getting higher at 21 without day or weather, at around 310 enhancing magic skill

Stoneskin's effect stops at 350 (without gear mods)

I would like to see the caps at least made possible to break so these spells dont slowly become useless
