well, its a meta for a reason (coz people spent like alot effort into making that formula)
and, about the blind thing… i guess u are new player… how many lv330 character do u have?
u can formulate your own stat n strategy if u made enough toons… different class different strategy
also, stat n equipment isnt much of a problem now.
u can buy costume with silver n exchange it to medal for stat reset potion.
lv10gems u can afk-farm silver like a bot
yugimori is just legendary like sao kirito.
full dex or high dex low con is meta for physical class (coz dex give evasion)
phy dmg can be achieved from hair accessory/gem/transcend etc
str is overated now until imc being imc, they fcuk the whole meta up again with so called patches/fixes
