Um, what about the whole James LaBrie interview thing? The one where LaBrie said he wasn't sad about Portnoy leaving, then Portnoy started deleting any threads pertaining to LaBrie, and then Labrie had to say, "Um, okay, this is what I meant," and Portnoy was like, "Errrrr.....oops, sorry, that was really lame of me to take it the wrong way." You guys know all of this happened in PUBLIC, right?
edit..
Plus, the constant blaming of the other guys in DT and the jabs like, "I e-mailed them and I never heard back from any of them." Does that crap really need to be all over the place? If I were in Avenged Sevenfold, I would have done the same thing - he would have been canned a long time ago.
