I've read numerous times he was the biggest hip-hop head in the group, and he didn't like the change in direction that started with Mezzanine.

3D said around the time of 100th Window that Massive is more a collective than a group, which is why people have came and gone as they pleased (Tricky, Mushroom, Daddy G, Davidge).

3D is the only person who has been on all their albums.
