What if you focus that stat on what purpose of it.
Ex. Str - Phy.attacks
Dex - Crit rate, eva, strike, small portion of crit damage
Vit - Hp, hpreg., phy.def
Int - magical attack
Wis - mp, mpreg. M.def, crit rate small portion of m.critdamage.
And you already adjusted the crit damage of fighter and rouges to 150% till 250% includes all buffs passives and philos.
Why dont you put also crit bracket for mages . which i mentions that wis gives crit rate and damage so that they dont depend on fortunate magic and twinkling chuchu.
Also put limit like 150-250% m.crit damage . right? which i suggest to put crit damage to wis stat so that WIS will be helpfull for those crit mages esp. Soul Arbiters or any crit mages. So that even mage think for their stat and make strategies for their build .
P.S sorry for bad english :c
