Disagree completely, Potion users - it's their choice not yours, you don't like that, you picked the wrong game, stands to reason a caster would devise a way to restore spell ability in a real life way anyway.
The restrictions are already ridiculously overly exaggerated by substantial amounts.
I play both melee & casting & I H A T E the cool-downs totally-to the point if I was using these skills in real life - I'd devise a by-pass to the "cool-downs" - I think it's ridiculous that a cool-down even got instituted. Reloading a fire-arm is one thing, a caster with spell components & a book of spells only needs to recite the incantation for the spell to be effective. the stronger the intellectuality of the caster should be the deciding factor to the potency of the spell...
Potion restrictions to restrict Potions designed to restore an already inflated restriction is ridiculous IMO....
