Archer/Hunter Help Rainbow Archer Spell Spam Build

I have a class build for lvl 88 rainbow archer with an emphasis on spell spamming

/s/u623ij (can't post links yet).

Right now though, I don't really know what to think of it (specifically have concerns about how viable the morph set is currently). If I could get any feedback on how good the build is, and how to improve it, I would greatly appreciate it.

 

if you use morph, use it all

don't worry about the hp and mr, the def and spell costs make up for them
