OK so i am lvl 2x archer(used to be a lvl 43 archer, but quited, other story

)
So i really want to be a hardcore kiter.

But the problem is i do not what build i should use. Currently i am using a 25 SPR/ rest STR build. But alot of people say DEX is very important for a archer. So i came up with this build 25 SPR/25 DEX and rest STR

But i am not sure if the DEX will be any use after lvl 60(i am looking to use DEX for evasion, not aim)

Plz help me out!
Thank All
P.S. How do u put a picture(or signature) under all of ur posts and how to put a picture as ur name.
