I've been running Heroic dungeons to gather up the best pre-raid PvE gear I can get (almost . . . I'm lacking a few items, IMO, but I've gotten my iLvl up to 467), and trying to practice my group healing. I also do random BGs (accumulated full Dreadful) to help with my healing skills.
I'm not really confident, though. I've done dozens of MoP heroics and have only wiped a few times, but in almost every instance I do, there are several times when the whole party drops to 1/2 (or some 1/3) of their health, which I always struggle to bring back up. My single-target heals are mediocre, but I'm downright bad at AoE healing. Which I'm sure is a major point of raid healing, yeah?
I dunno, I just feel like . . . LoD is ~20k hp per person (I glyphed it), and Holy Radiance is ~20k, and about 10k to anyone nearby. And that seems really, terribly useless compared to everything else. But then again, my AoE's bad.
I'm an ace at hitting Holy Shock every 6 or 8 seconds, at least.
Mana is not usually an issue. I think the times when I run low on mana is usually when some party members get clumsy and take lots of unnecessary damage, and then I also get clumsy while trying to save them.
Battlegrounds . . . I think they've helped a bit. I'm more willing to go into them and practice something new than risk ruining a dungeon run. But it seems like hit-or-miss as to how well I perform in them. Sometimes I'm a god among mice, othertimes I can't heal teammates to save even my own life. Not really relevant, sorry.
If I could have some advice on raid (LFR) healing, I'd be very grateful. I might not be on to reply later . . . so, thanks in advance (if anyone responds).
