Wrong. The average per cast was 4.05/4.05 per GCD because Enhanced Scatter could not proc itself. It alternated between a guaranteed 3/3 on one GCD and an average of 5.1/5.1 on the second for an overall average of 4.05/4.05 per GCD. This is less than even the weakest Verspell.

It's a curiosity, then, both that a tradeoff for the greater potency per cast is a reduced Mana income (which is not something we face in the main rotation), and that our AoE quickcasts generate more Mana per cast than Jolt.

As I said, unnecessary and largely fueled by personal opinion, I just think it's strange and slightly weakens the impact of... well, Impact.
You're completely ignoring Verflare/holy into Scorch which is the identical situation to the AoE rotation. Also, if Impact doing almost twice the damage of Verthunder/aero 2 isn't impactful enough for you then I don't know what to say. It makes complete sense that mana type focused spells generate more mana because of that focus and the generalist spells don't. It's practically a trope.
