you realize that you are making no sense?
yeah you throw your shield, spear and axe.... do it ask dexterity for this? nope.... you litterally use all your strength for toss this heavy stuff far and hit someone... no dexterity into this... simply brutal strength.

all you want it's overcomplicate thing... you are simply trying to justify you preference from other game into this game. the point is... the rule of the game are:

- all melee class use STR for them capacity
- all ranged magical class use INT for the damage
- all ranged physical class use DEX for the damage!

why try to make thing more complicate! why try to force people to go look for another stats simply for 3 attack? it's stupid! Ninja will be a melee dps class, then it will need STR! move over it and accept it!

all the people saying ninja will be dex based... are saying why? because of datamined information on the 2.28 patch... the ninja is coming in the 2.4 patch... you have at least 2 patch between both.. you really think what you found into the patch of the 2.28 can be seriously take as reliable information? no!

finally, like said by some, in the futur we will get more and more class/jobs, is not the time to overcomplicate all the math behind the skill simply for... i don't even see why you are wanting to make stuff more complicate actually. if you had play monk in the V1... you will know that it's pain to have 2 different stats for equip your class, and will never ever ask for it!
