One of the things that did hold it down was their uncertainty with regard to the controller role. Had they been dedicated to making it multi-targeting or debuffing, aspects of those wouldn't be so uniformly spread throughout most of the PHB classes, and it would instead be baked into explicit mechanics rather than implied or indirect ones.
Incidentally, I've fallen in love with the idea of a polearm-focused Martial Controller. It's brilliant.
