Trying to make a CoC Bow build. Will this work?

Going for a CoC bow build with Tornado Shot and some combination of fireball/arctic breath/arc. Though, I am not sure whether I have enough damage nodes to justify using the spells. I'm also torn on whether to go for Iron Reflexes or pure evasion + acro. Any other comments or advice on the build would be appreciated as well.

Well I start...
-Weapon ele dmg nodes are useless (damage comes from spells)
-Iron Reflexes isn't great either (I would use Acro+ Ondar)
-147% life is not enough if u plan on leveling past 90
-pick the projectile dmg nodes instead the spell dmg nodes at scion start
