I have two healing toons, a priest and a druid both in different guilds. I play on a US server even though I'm in a GMT+8 timezone and thus can only raid on weekends. So over the weekend, I tried healing Ulduar 10man on my priest and it was refreshingly fun.
My guild wiped alot, and I forgot how expensive it is to raid a fresh content from the numerous tries and wipes, flask, food, reagent buffs and the dread repairs. I think I probably need like 100g each raid day even on my clothie toon.
