The problem with some addons is that they trivialize encounters so much that future content is designed around having those addons. This forces anyone who doesn't enjoy data crunching to use them. I am a min/maxer like many and I do miss some of the required raid addons I used in WoW, but I have to admit it is also quite relaxing to be free of them. I just hope they strike a balance so that you have some choice in regards to the half dozen raiding addons that are required to even clear trash. I love them until they become a required crutch for encounters. Some of the raid boss mods from WoW (ie. Deadly Boss Mobs and others) actually turned many encounters into a dumbed down version of Simple Simon.
