Taking Deftness (CB) as an example : The New Potions are a downgrade from last expac Thaumatic and Bloody Tooth have the same main ingredients the only difference is the rare. Shadeweave Root for the bloodytooth potions is much rarer than Thaumic Material Twark and Abyssal you swap 2 abyssal anglers and 2 Thalumbral roots....and get 8 vs 13 cb?
Fortitude is even worse. Abyssal using common ingredients gives the same 2.2% mit for 30 min that Bloody Tooth Gives.
