The issue is that in expert roulette we don't /need/ to heal full time. There is very little reason I can't remain in cleric for 80% of a dungeon given the difficulty of the two new ones released so long as I know when tank busters are coming and plan appropriately. Even some of those can be completely negated by HoTs. Also...2 in 60? You're doing way better than I am. I've missed up to six times in a row with Stone III. Holy misses half the targets on a regular basis which is really frustrating considering its stun effect is a nice utility that is suddenly not reliable. Aero III? Same deal. Often misses half the targets and I've had it miss all but one in a pack of four at least once.
The thing is tanks now, on average, have more HP, the dungeons are abysmally easy and there aren't a whole lot of mechanics that keep healers occupied otherwise so it's left us in an awkward situation with like expert roulette. I can meld accuracy just to have something to do but that will negatively effect me when I move on to do harder content where I don't have as much need to dps because the incoming damage and mechanics are more punishing. In which case I'd rather have stronger heals, more mana etc but I'm being forced to make that choice. It feels like they forgot to commit. They are discouraging healers from dpsing as much but didn't give us anything to do in its place? In fact we have more openings than ever and they even gated the new dungeons pretty heavily to keep people from doing overly large pulls. Personally I feel like they need to give healers enough of a boost in accuracy to not need melds or at least limit the misses in casual content /or/ they need to back track, stop giving us so many dps skills and properly challenge us at all levels of content. Which is to say, they need to make up their minds.
