Best fill stats damage output on weapon and armor?

Hi guys just a newb question. I don't know if its already been posted but im just curious coz im making my 1st fill stats. So im not sure which will be better for weap and armor fill stats? Should I go Attack% or 20% Damage to element for dps in weapon and armor?

 

For damage, ele is obviously better than atk% in term of damage output (on responding targets), but in return you need 6 of them for each element, which is rich man's thing
But keep in mind, element filling for armor (most of the time) require bag expansion (real cash) or a hell lot of character (to expand your material limit). Weapon doesn't need this tho

 

I see. so its better and cheaper to make on weapons then and its much better buy the armor instead.. Not worth to spend cash just for that. XD Thanks man. Damage to Elem it is.
