I get the disappointment, but I never saw Roy as an integral part of Bruce's live act. He did exactly one tour with them, hired out the Guru on the next tour, I don't think he did the 2002 gigs where Bruce brought Chris Dale back, and no tour for Tyranny.
Granted, this is coming from someone who did get the chance to see Roy onstage on the AoB tour. It was cool to have him there, but he's not a "showy" player, much like Adrian. Eddie Casillas on bass was a lot more of a live performer, if you know what I mean, doing the Harris "gunning" the audience, etc. Roy and Adrian stayed where they were and played most of the time.
