Just random dreams:
AST
Eclipse: Turn the effect of the next Aspected Helios or Aspected Benefic like if you was in the opposite stance. 40 sec Cooldown

SCH
Infection (Trait): Make your Virus Spreadable with Bane
(SE made a skill called virus and it doesn't spread among enemies? It sounded strange to me since I got it xD)

WHM
The damned Y'Stola skill XD: Long cast time (~8 sec), when the cast end if you are on Cleric stance it AoE hit hard enemis, remove your cleric stance and make you unable to use it for 30sec.
If you was not on Cleric stance it full your party HP.
Long cooldown.
