I just started Cata after a long hiatus since mid-TBC, i played as a resto shaman. I realize theres a big difference in how dungeons/raids are run in Cata compared to vanilla/tbc, everyone just rush through everything, no CCs/Offtanks/Food&drink buffs/soulstone(WTF)/not even strategies, everything is tank and spank.
Need some advice on how you guys heal as a disc priest, im not used to the way they run things now and the big hp pool + low healing power + scrapping of CCs and oom frequency makes it worse,
Would appreciate any advice, healing rotation or add-ons and whatever that helps.
