Toss a blessing of kings on there and you're talking BIG PIMPIN healing power.
If there are any I've missed or if some of these don't stack please say so.
On most AQ fights (and I assume Nax, following their encounter design progress), I'd consider a Titans more useful than a Distilled Wisdom even on a healer. On some of these fights the healers go through such huge amounts of mana that 2k isn't gonna do a thing, whereas 1200 extra hp might be what saves them from getting KOd by some RSTS.
I am the same as mosh, 2k int makes no difference at all with the amount I burn through in one boss fight, 1200 hp on the other hand made a huge difference for me. When we were learning cthun, 6500 green beam? oh well, leaves me on 700hp.
Consumable buffs I have used recently are mageblood, chimeroak chops, zanza, titans, elixir of fortitude, green grog and brilliant mana oil.
That extra cushion of more stam helps oh so much more than some silly int.
