A potential healer DPS rotation would have to be kept very simple as they would have to be able to stop it and be a healer at any time. For WHM it could be a simple as every 3 or so Glares cast you get access to an instant Banish or some other instant aero/stone/water spell. AST could have a GCD spell that has its cool down reduced every time you cast Malefic or Gravity, as well as be given Double Cast from PVP. SCH could get a DPS fairy to summon, and it works like Fray/Queen. SGE they just need to make some tweaks to the Toxikon system to allow it to be more aggressively used.
