The problem is, if someone wants to meld stats that would help not only healing but also damage, like Det, Crit and SpS, they would be left with a large gap from Acc cap (I have 354 accuracy with no melds, and Jesus Christ, I miss a lot), making it near required to have acc melds.

SQEX need to decide about healer dps. Do they endorse healers to DPS? Then add an accuracy buff to Cleric Stance or bring back Accuracy on gear. Do they not endorse? Then remove CS from instanced duties. The way we are now, with a wishy-washy, fence straddling position about healer DPS and accuracy can't go on much longer: I really doubt that, even with a fully melded raid set of grade V accuracy materia, we will be able to achieve accuracy cap when the ilv reachs i260 or i270 (wich won't take long, probably 3.5 or sooner)
