I was a BC baby. When I rolled I thought i was going to be a tank, the guild I was eventually recruited into had me dual spec, before dual spec. I was Ret for progression mostly, but I tanked when needed especially on off nights when we ran alts through old content. I always tried to be the best I could though even when I started out I was one of those Rets bah they are useless. Some how I came to love it.
I started as a BE, why I started becoming serious in WoW, to be a horde pally. I didn't like the ally side on my first server. I tried in Vanilla ended up shelving it. So, I worked my way in spent a lot of time doing off-nights after I was recruited by my raiding guild. I was understanding of the lack of need for a Ret in progression 25 Raiding, I eventually wormed my way into a top spot. I was reliable, I farmed when they were raiding while listening in on Vent. They needed resist gear, I was farming motes before they asked. After some time I started hanging around near the raid portal, just being available. I donned my tux and had a bag full of gems, and made sure they all knew if they got an upgrade I was ready to cut them gems to get that piece of gear ready. In Mount Hyjal They used to have a super superstition that Archi couldn't be beaten if I wasn't at the instance portal.
In BT was when I really made my break-in from farm raider to progression night. The guild leader went on Vaca and the melee officer was leading he stacked the #%!@ out of melee and I was one of them. From then on I became a main raider and I proved myself. I knew it all back then, I was a seal twister (BEs know what I am talking about Command and Blood). It was tough going I just couldn't beat some classes no matter how on I was, but I was always excited when I was making Top 50% (damn rogues).
I remember the really fun fights back in BC, like the ones we just couldn't do. LoL remember Kaz'rogal. Ooooh boy that was a fight, especially for Ret. We just couldn't keep our mana. I did everything I could used all my CDs correctly, Mana Pots, Dark Runes, anything that was able to sustain myself. Even with reducing my rotation to just to CS just enough to keep up the judgments to help the rest of the raid, eventually that fight boiled down to me running off to a corner to blow up alone.
I loved BC it was still a highlight for me, any time with CeA (my first guild) was times I remember fondly.
