Like everybody, I try not to be the typical rock drummer & crash on the downbeat of every measure or after every fill or transition. Sometimes the music just needs it. I feel like I really used to over use the crash, and I have worked on having less/making more dynamic use of the cymbals.
To some of the other comments about being a crutch or only being a timekeeper etc. I agree that a drummer should be able to express themselves & play their instrument as much as any other. However, I have always felt like it was my job to control dynamics, tempo, and signal where the changes are. Almost like a conductor, if everyone follows me we will be alright (as long as I don't F' it up, lol). I wouldn't want to play with people who didn't know their music or couldn't feel the beat, but I like to be a solid foundation of a group.
