What fights are you talking about here? You mean the scripted experiences the combat designers create, I assume? The DDR-Memory Gauntlets Hallarem mentioned?
Personally, I agree with Hallarems sentiment, as I too have no enjoyment in having to Memorize 256 Steps of a dance to come out victorious and would much rather react to things than resolve them. For example, the heart spam in M2N - hugging the boss the entire time while dodging AoEs left and right was much more engaging and fun for me than resolving Hello World or Light Rampant in Savage. Stopped raiding in 6.0 cause I felt more annoyance in raids than enjoyment.
People look for different things in video games. Whats fun to some ain't fun for others.
