Since Cataclysm has come out, I've done maybe 9 or 10 dungeons (Throne, Stonecore, Vortex, Lost City, and the other one like lost city [can't think of the name atm]) at various levels. I'm now 85 and I can safely say that healing these got harder as I grew in level.
Now, I'm not giving up on healing or whining about how difficult it's become. I kind of enjoy not being bored healing dungeons, mindlessly clicking every now and then. HOWEVER, there is a certain level of (hesitant to say) ridiculousness to healing dungeons now.
Besides the fact that tanks and DPS still act like this is WotLK and they can chain pull/ pull without waiting for my mana/ DPS not watching threat/ standing in the stupid/not CCing... that just doesn't work now. If they don't get their stuff together, dungeon runs WON'T SUCCEED. I can only do so much as a healer keeping everyone alive. But when everyone in the party is standing in aoe/not silencing or CCing the aoe-dmg mob and therefore taking 15-30k ticks, my heals aren't fast enough and my mana pool isn't large enough for that. Still, despite my best efforts and wipes/deaths 80-90% of the time not being my fault, I still get told I'm a terrible healer - which I know not to be the case, especially from the compliments I got back in Wrath.
/rant about DPS & Tanks.
Back to Shaman Healing. Like I said, I'm lvl 85 now, and I dunno if it's just my gear or what (maybe just the tanks and DPS needing so many heals), but I run out of mana INSANELY quickly. I have an almost 70k mana pool, and have used all the gear I've found (questing and dungeons) that has Spirit on it for combat regen, but run out of mana EVERY trash pull of greater than two. Don't even get me started on Boss fights. I'm blowing everything I have at my disposal to be able to continue healing maybe halfway through the fight.
Anyways, I've noticed that Healing Surge and Greater Healing Wave (used mostly when I need fast, big heals on the tank or a stupid DPS) cost about 6k a shot - for me at least - which means I can do about 10, maybe 11 or so, if I don't use a ton of mana on other, smaller moves (Riptide, etc.). Even Healing Rain costs 10k mana for me.
And yes, I have all three points in Tidal Focus.
So, basically, am I doing something wrong to have these huge mana costs and frequent OOM "Oh crap..." moments, despite my best efforts to the contrary, or is it the groups that are sucking and draining all my mana, or is it Shamans just have a larger burden as healers now?
*Again, not QQing, griping about undue healing hardships or how Blizz is being "stupid and unfair", I'm just asking an honest and legitimate question so I can better myself as a healer by knowing what to look for and what I'm up against now in Cataclysm.*
