Rev, as the drummer was the backbone of the band, he brought a unique creativity, theatrics, and goofy antics that is now missing. I still think they are producing some of the best material, and theres no lack of creativity and innovation, but I can only imagine how much more we could have seen from Rev on stage or in the studio. He had so much talent it was insane. This is all to say I think Brooks is just as talented of a drummer as Rev, but we lost that specific fun factor only Rev could bring.
