When I say burst I mean roughly 2.5-3 sec before the tank gets hit again, and you have to consider lustrate. Bene isn't reliable with a 5 min cd but lustrate is potentially 3 times a min.
Whm burst heal: DS Cure 2
Sch burst heal: Fey illumination, adlo, rouse, embrace, and lustrate. The adlo and embrace can be cast together and lustrate is off the gcd.
Your cure 2 crits, great, if adlo crits the shield is doubled.
There is no comparison, even moreso if you consider that with any healing debuff will wreck a whm's heals but sch lustrate isn't affected.
My whm is ilvl 90 with a det build. My cure is around 1100 and my cure 2 is 1700-1800.
My raid sch is ilvl 82, crit build (what else). Physick is around 1k and embrace is 650. When his adlo crits I sit back and take a break.
Why are we talking about pom? its 5 min cd.
If you want to factor in ds you have to consider fey and rouse. also keep in mind the sch have better dmg mitigation and preshielding. with less threat and better mana management. Go ahead and spam cure 2 for a bit and see how your mana is doing crumpled in a dry heap on the floor while your sch buddy is wishing he could give you some of his. This has happened to me a few times in dumb situations, like a tank without cd's tanking two dreadnaughts that ate spiders in the last phase of turn 4. I think I nearly went out of mana with bard song, sch was at half. I get that you aren't supposed to heal stupid, but a sch borderline can.
I was talking with two raiding sch from my fc yesterday and it was funny to listen to them talk about how whm regen should be off the gcd, or stoneskin improved or something. Kinda makes me giggle. Personally I wouldn't mind medica 2 being changed to just a hot. Remove the burst heal and lower the mana cost to compensate. When I need to raid heal I'm using medica or cure 3 anyway. Give us the option of having a baby heal in the background.
But don't misunderstand, I'm not saying whm is terrible or sch should be nerfed. But a few qol changes would really help. Heck, i'll even take bene actually being instant and not having the tank die as the heal goes off and the cd wasted.
