Hi dex/str/luk-that big of a deal?

From personal experience, my first WK didn't hit over 3k damage until it got to use it's doom bringer (97 attack) at level 70 and it had 90 base DEX while my current page with 5 base DEX has been dealing 3k since level 50 with it's japanese map (80 attack). My old WK at the time had weapon attack coming from only 2 sources when it first hit over 3k (97 att DB and 5 attack pill) to total a 102 attack while my page had 3 sources when it first hit over 3k (80 att JM, 10 att gloves, and 12 att pot) to total a 102 attack as well. so for a warrior, the DEX difference I had was worth about 20 levels of STR for damage.
