Given that Circle and by extension PH is on a 2 minute CD I would see no problem with having PH just give you 100 gauge for 2 Enshrouds and call it a day if they wanted the Reaper kit to stay the way it is.

Arcane Circle might be more fun to use if we could just keep getting sacrifice stacks and it's a team effort to give the Reaper orbs for constant PH's for some great AoE cleave but also big Shroud gauge gain.

I'd live with the ability to get 2 Harvests off just to top off the gauge even.

But I agree with you that it's become bring the job not the player when it should be bring the player not the job.
