Save yourself the headache, he's more than willing to throw insults, but the second you raise heckles even slightly, he'll go 'oh woe is me, everyone here is so mean and always attacking me'
Anyway, the unfortunate truth is that yes, you do have to use Misery's even if there's no healing needed. Since Misery is equal to 4 Glares, by sacrificing three Glares outside of raidbuffs, you can move them 'inside' the raidbuffs in the form of Misery, moving you from having what should be, say, eight Glares inside the raidbuffs, to a pseudo-11 Glares (7 real, 4 via Misery). Annoying, but it is what it is. Personally, I hate it. I don't like throwing out healing when it's not needed, I'd rather hold the Lilies in case I need em for something. Sure my parse takes a hit because of it but I'd rather that than getting caught with my metaphorical pants down by Reaper Ronald standing in the dumb and being unable to heal them before their untimely demise because Tetra and Bene are just not enough OGCD tools compared to the other healers SE I am asking once again for a second Tetra charge thank you
As for Rapture and Solace, I'd only ever count one of them. And I'd only ever count one of Engagement or Displacement, or Fleeting/Forked. If someone else wants to count both halves of a pair then more power to em, but I'd call it disingenuous to do so. I would count Verholy and Verflare as separate 'skills' due to their effect on the Mana gauges, and their 'if that mana is lower, you guarantee the proc' effect, but I wouldn't consider it another hotbar slot because Aero/Thunder turn into them. Same with Jolt/Scorch/Reso, separate skills, not separate hotbar spaces. And when people criticize the idea of healers having more damage options, I assume it's more a worry about 'where do we put all this new crap on the bars', not 'I have 5 new damage skills (they all intuitively take the same space as current actions, eg a new AOE damage skill for Sage that is 'Eukrasian Dyskrasia' (yes I know it's contradictory))'
