First, I'd like to say I played Retail from Vanilla up to the Patch 3.3.5 in WotLK and looking back, I don't regret anything.
Even though I was forced to play as a Holy Paladin in Vanilla, I'm more experienced as a Retardin and a Tankadin to be honest. At this moment I'm a DPS and some what experienced with almost all raids, except the Vanilla Raids because let's admit it, people wiped more than actually making it through raids back in the days.
I'm planning to dual-spec Retribution and Protection once I have a steady economy with professions and what not.
In Short, I've played the class Paladin ever since Vanilla and you can often count on me. Also, if you ever need help with anything (Since I'm LvL 80), I'm more than willing to help a fellow guildie!
