Just got out of an A6N. I was running SCH (i213, Gordian Codex) and had a SCH partner (i230+, Hyperconductive Tetrabiblos).
Naturally, I was the main healer to the tune of the only healing that my healing partner used the entire instance was Embrace and Energy Drain. I had Eos out as usual since I never trust DF healers. And I don't mind if the other healer only does DPS. I can solo-heal all of Midas Normal on SCH without issue.
But...
At the end of each encounter, the other SCH would end with DPS comparable to mine. 300 v 2000 HPS with 650 v 600 DPS on Vortexer, for instance. Like. I don't care if my healer partner is super over-geared and wants to DPS and force me to be the heal slave. That's fine. But if you're gonna do that, don't be shit, basically. It's really frustrating to be forced into the main healer role and then nearly beat out your 0-healing off-healer in every fight. Like. It makes me wonder what they were doing, since it implies the two of us hit essentially the same amount of DPS skills in the encounter AND I pressed a bunch of healing skills, too. What were they doing during the times I was healing? Hmm.
