So I'm starting out my first raid (normal 10) ever this week and I'm not really sure what consumables I should have and bring. I'm Arms right now because I don't have two high enough weapons. I have the best strength food available, but what flasks and stuff should I bring?
Melee isn't awful for Challenge Modes; you are. Melee players are a liability for the windows of time in which a tank keeps an enemy mob faced towards them, resulting in an exorbitant loss of damage or death. Melee players are a liability for people who keep rooting mobs next to them. Melee are a liability to a healer that cannot heal.
