Consider even the absolute most barebone way RDM AoE could have been applied:
What would that mean, then (tuning aside)?
- You could Scatter-Scatter, as before, for 6|6 Mana and 280n potency.
- You could Scatter-Veraero or Scatter-Verthunder, as before, for 3|14 or 14|3 Mana and 140n + 370 potency and chance of Verfire/Verstone procs.
- You could, newly, Verfire-Scatter for 3|12 Mana and 450n potency or Verstone-Scatter for 12|3 Mana and 450n potency.
- You could, newly, hardcast/Swiftcast Veraero-Scatter or Verthunder-Scatter for 14|3 or 3|14 Mana and 510n potency and chance of Verfire/Verstone procs.
1 button in total required for non-Mana-spending AoE, but now you have a significant AoE damage increase from procs generated and more reason, situationally, to hardcast.
