Aye. Since my coheal and I have an understanding that she only heals if she feels there is a need to, I get to push as much healing as I can.
Far more fun than DPSing in my opinion and she prefers DPSing. So I'll never get to purple DPS anyway. Sometimes, when everything is good I manage a blue one.
The result (last weeks e1s, second kill IIRC)
Lily both adds, yup, that works. Even had a try in which I could do it twice but usually they don't live long enough and I am reluctant to pump lily heals into overheal just to get the DPS goods. I try not to waste any lilies but ultimately, I do not plan my heals around DPS maximization. I plan them according to the needs of the encounter.
Boss +1 meteor would theoretically work too but I don't think our tanks bring Eden close enough.
