Do you think that merging together the raiding achievements from WoTLK would be a good idea? With patch 4.0.1 came 10 and 25 man raids sharing lockouts and loot to be the same for both difficulties. It is no longer needed to do the same achievement twice in Cataclysm but on either 10 or 25.
I also think that some achievements should be feat of strengths as regular players would never be able to complete them. For example the Battlemaster achievement or perhaps achievements along the lines of achieving in the top .5% in a rated BG. It would work similar to the way "Insane in the Membrane" feat works. Thoughts? Would make achievements A lot more fun knowing you could possibly get them all rather than remembering that you'll never get "Veteran of the Alliance" or w.e.
