Blast Rain/8 Artillery Ballista Non-Crit Ascendant(berserker/raider)

https://pobb.in/tbzAPmWu89NI

Blast Rain Ascendant, non-crit using the new keystone. Most of the damage is coming from the artillery ballista and remainder as blast rain attacking and applying cover in ash/combustion (cover in ash from alt quality). Playing this build on a lower level character in game I've seen merit in Focused Ballista or letting them be automated so I'll probably play around with both until I've decided. This build is similar to TN_Sylar's build here https://www.pathofexile.com/forum/view-thread/3145720 specifically for using the ballistas to get the single target dps high enough to be comfortable. Currently the dps calculations are to be as modest as possible for what I think is reasonable so Berserk is not enabled, only 20 rage etc.

My plan is, if having problems getting enough accuracy for the keystone, I can swap to Juggernaut ascendancy point over berserker until I get enough on gear or the tree to swap back. I have 3 tiers of gear and a leveling tree to sort of guide through the way I think it would go, I believe the bow in the higher tiers is not that close to what will be possible with the 2-hand and base bow damage changes but does give a rough estimate of a decent bow so the damage can scale a bit further beyond.

If anyone has any advice or sees any improvements though I'm open to suggestions but, let me know what you think if you take a look!
