Disturbed and Dillinger Escape Plan developing feud

Dillinger Escape Plan and macho-metal act Disturbed are apparently developing a bit a feud. While DEP noted that:

"[They were] practicing where they were going to walk and when they were going to put their leg up on the monitor and pose, That was weird for us. There are times [during live gigs] where I don't even know where I am.

which led to a bit of defensiveness from Disturbed:

When we do a bigger production, there may be certain lighting cues for certain highlights of the show, but I wouldn't call it 'posing,' just a cue for our lighting guy, so he can add more drama to the set. If [Dillinger] sold some records, and were at the level we're at, maybe they'd see that, for bands like Kiss and Metallica, there are certain highlight points during a set that you want to focus on.

If they're saying it because they're haters, why? Because we sell millions of records and lots of tickets? It sounds more like jealousy to me.

DEP released Ire Works last year.
