[RDM Suggestion] AoE Attack Phase

[Mhaeric]

Scatter 3|3 + Veraero 11|0 + Scatter 3|3 + Verthunder 0|11 yields 17|17 mana.

Scatter spam is 3|3 + 3(0.75(3|3) + 0.25(8|8)), with an expected yield of 15.75 | 15.75, a minimum of 12|12 and a max of 27|27.

Alternating spells yields 5|5 more than the minimum, but only 1.25|1.25 more than expected.
The best use of alternating spells is to keep a stronger mob even with the rest of the group; not necessarily to generate more mana.

You left out Enhanced Scatter in your first one so it's a 75% chance to get 17|17 and 25% chance to get 22|22 for an expected average result over time of 18.25 for 4 GCD. Your math on the second is wrong too, I think, and its expected average result is a lot less since you won't always get 3 chances at the proc. I.e. if you proc then your next one is guaranteed not to proc. The max at any rate is 22|22 not 27|27 since you have to at best alternate Scatter with Enhanced Scatter. I'd have to sit down and calculate it out a bit more, but don't have time atm since I'm on the way out the door to work. Either way, even in the short term it's always better to use the alternating single target one. On 3 mobs anyway. Once you get more than 3 then the potency output increase outweighs any balance discussion.
