Well your answer is right here!
G'day! Im Bubbleòseven (aka Rzsupra) and im here to tell you that i will help you get what you need! You may have seen me in trade spamming such things as "LFM for Icc25 Heroic including LK" or "LFM Ulduar 25man Drake Run!" If you have then you know what im all about, which is giving back to drakaians by running old content for either 1. Fun, 2. Achievements, or 3. Transmog.
If you are interested or needing achievements for a certain old content raid, weather it be Naxx 10 or DS, or even just doing a BC raid for xmog, plz feel free to pst me in game or mail me in game (alt 149 = ò), or leave a reply in this thread with the raid u want to run or the achievement you need and ill get back to you to organize a suitable day and time for you. On that note if it is a meta achieve you need such as "Glory of the Firelands Raider" these usually will take 2 weeks just to make things easier for everyone, but there are some that can be done in 1 run.
If you have any further questions plz feel free to in game mail me me or pst me :)
Thank you all for your time.
