I'm not sure if you're being sarcastic here or not, but martial controllers absolutely make sense. Artillery-based martial classes that strike multiple foes, inflict status conditons and high defensive powers are entirely reasonable.
Okay, martial controllers don't make sense in any WotC D&D setting. If you've got effective man-portable artillery, then personal firearms are common. If your artillery is non-man-portable, then you've got a character that doesn't work in a D&D party. If you're playing 4e Modern, or maybe even 4e Iron Kingdoms, then you can have your martial controller.
just about all the classes...and the gnome.
I am a little worried about phb2 classes outshining phb1 classes.
