I've been Disc for the past year or so, healing my guild in raids with no problems (we're a very small guild with 13 members that does 10 mans), so I'm mostly 232 geared (couple of 29 pieces).
With 3.3, I thought I'd try Holy for an easy life in all these random heroics. It turns out that HoR Hc last night was simply impossible for me to heal. Too many people taking too much damage for me to keep up (we wiped 5 or 6 times on the first pair of bosses, before we even got to the bosses sometimes). I was rolling PoM, CoH, PoH and GH/Renew on the tank, but I couldn't keep everyone up.
Then (and this is probably the most annoying part), the Ret pally suggested we switch roles, so healed and I dps'ed and we did the boss first time. We then switched back and I failed on the gauntlet part.
What should I be doing as Holy to combat all this party damage? I fear that if I went back to Disc it'd be even worse.
