I was at first a hunter back in the days in vanilla, I cleared up to AQ 40 and opened the gates up with my fellow guild. After the long content of Vanilla, we moved onto BC. I wasn't too keen on playing my hunter again and I wanted to play a more engaging role within the game. This role so happened to become healing. I decided that I'd choose the priest class to heal is as it seemed priests had the largest toolbox of all healers, making healing alot more engaging in fun. To my thoughts, I was no let down by this notion. I thoroughly enjoyed healing as Holy in BC. Although the whole Circle of Healing spam shouldve died back then too, but there were still things such as 5 second rule, downranking, and keen decision making while raiding as a holy priest in Burning Crusade.
However, I will be honest here, I was awful back then now looking at how I played. I click targetted to heal players, used default grid, and my UI was a cluttered mess! After looking back at some screenshots and videos of me playing back then I can only wonder how I managed to pull it off! Towards Wrath, I left for a new raiding guild, I mainly still played holy towards the beginning of wrath in this casual like guild. When Ulduar came out, I took my priestly skills to a more progressed environment. It was there were I fine tuned my playstyle as holy and discovered my new found love of a now popular healing spec, Discipline. As much as I liked holy, I enjoyed the playstyle of discipline and how proactive you had to be in this role. Alot of people deem discipline as "faceroll" and "mindless", but to become a great discipline priest, there are signs that set an efficient one from a bad one. I stayed with this current guild till ToGC and they pretty much died there.
ICC came out and I moved onto the guild <Seriously Casual>. This is the current guild I am in and I just overall love the environment and teamwork we have to progress. I was mainly discipline throughout ICC with my job being to pre-shield raid damage and top em off with Prayer of Healing. We came out of this tier as US 35, and I was very proud to be a contributer to this ranking.
Now that Cataclysm is out I am still playing my priest. I started off playing as holy in the very beginning. I leveled as holy through dungeons with some fellow guildies to power level. As soon as I hit 85 with 1-2 days, I moved on to attempting heroics. Getting used to it was actual difficult at first, but it was still manageable at the same time. Id have to stretch my mana conservation abit on some of the encounters, but in the end always survived and kept my groups alive. This was a pretty enjoyable time first learning all the heroics and also learning how to generally play holy better. By the end of the first week of Cataclysm, our guild first set foot in Blackwing Descent. We were first attempting to do Omnotron Defense System. It was to say, a really difficult fight at first! We were hardly in full heroic gear at the time and I always barely had mana left towards the end. It was a really fun time first learning how to do all the normals. Now we've stepped into the heroic modes of these encounters and my main role is back to discipline as of 4.0.6. I'm really enjoying the role I have within my raid and will continue to stay discipline to better help our raid in progression.
