I think this would be a great idea. We can have some type of prerequisite via merits, mag trials, etc. a Couple of Examples:
WHM- Benediction aftermath (highest tier of regen for corresponding level for pt members)
RDM- Chainspell: aftermath (RDM gains the effect of quick magic for 2 minutes)
PLD- Invincible: aftermath (PLD absorbs pt emnity for 60sec)
WAR- Mighty Strikes: Aftermath (WAR gains 100% DA for 60sec)
SAM- Meikyo Shisui: Aftermath (SAM gains the effect of regain for 2 min)
and so on, thoughts?!?!
