I'm looking for a change from my ret and fancy a ranged but in the past when I've tried my mid level mage I tend to panic when melee are on me and I can't get casts off. I realise it's all melee orientated PvP ATM but are there any casters that aren't frustrating to play? I don't care about what's fotm but I don't want to get stomped. Leaning towards ele/affli/frost, not interested in hunter. Any advice much appreciated.
