Why is StormBlood full of dps that never aoe?

[Kitfox]

I only AoE when theres 4+ mobs, otherwise im losing out on potency big time as RDM and gaining far less mana.

You should AoE already at 3 targets because:

Single target:
-9.5 mana / GCD
-288.75 potency / GCD

Scatter spam @ 3 targets:
-8.5 mana / GCD
-300 potency / GCD

Mixed Scatter + Verthunder/Veraero @ 3 targets:
-9.75 mana / GCD
-300 potency / GCD

Unless my math is off, it's pretty late.
