I was hoping this would change in the rework, so here again:

Confiteor requires Requiescat.

Request:
using Requiescat changes the Requiescat into Confiteor instead of having Confiteor on an extra ability.
(similar to Ninjas Phantom-Kamaitachi)

Sheltron & Holy Sheltron & Intervention.
Request:
Combine Sheltron and Intervention into one hotkey.
Using Sheltron gives you the buff, using sheltron on a party member gives them intervention.
(same as Gunbreakers Heart of Stone)
