PoE Rage Vortex, Rage Vortex of Berserking, Attack builds

So I put the following build and items together : The theory- Rage Vortex gets tons of attacks. lots of attacks + attack speed from Rage + some nice ranged elements potentially a ranged replacement for Blade Vortex in poison builds? Am testing this out as Pathfinder, but honestly this may be better as a Scion. Am using the Rotblood Promise + Chains of Emancipation combo to instantly generate full rage and maintain that rage since Rage Vortex really eats into your rage bar. I've noticed trying to attack too fast will

I have an idea to run Rage Vortex around. Basically, rather than use Redblade Banner or Chains of Emancipation, you'd use Chainbreaker, opening up your shield slot as well as your belt slot to max rage sources, for a maximum of 125 rage. To cover the rage costs, you'd obtain mana regen where most easily available, like jewelry and on the tree. Later on, you can swap out the 2 items for 2x Psychotic Axe(+10 max rage implicit). You'd stack enough mana regen so that you can use 1 rage vortex every 4 seconds as max rage. Could I ask for your input on this i
