I'm liking Sage so far, but I do have a few complaints:

Addersgall overcapping. It's a similar problem SCH had in 5.0 before the return of Energy Drain. For Sage, it's not so bad since Addersgall skills don't cut into DPS, but it is also a part of our MP management. I just generally dump it on Druchole just to keep Addersgall rolling. I think a button that converts a charge of Gall into Sting would be great. Sage has a slight mobility problem. Without Icarus or Toxicon charges, SGE can lose uptime. That's bad since its passive healing needs DPS casts.

Addersting as a mechanic. It's annoying that Addersting only procs on Eurkasian Diagnosis and trying to fish for it is a DPS loss. Basically, as it is now, we're going to precast 3 E. Diagnosis, then an E. Prognosis just to charge our Addersting. The above suggestion can fix that, but I doubt that's something they want to do since it's "just like Scholar".

Icarus. It needs either charges or a shorter cooldown. It's just not working as it is.

Phlegma: the 45s charge is awkward. It doesn't line up in burst windows like its supposed to. If it was 2 charges with either 30s or 60s timers, it would work much better.

Zoe: I'd rather this force a crit on my next heal instead of boost the potency. The crit aspect isn't as valuable on Sage as it is Scholar due to the lack of Deployment Tactics, but Eukrasian Diagnosis does still have a bonus shield on a crit.
