I guess Paladins just got the short straw although most minor glyphs are pretty boring. Perhaps in MoP all the lame buff cost reductions/reagent removals will be rolled into the classes and we'll see some more aesthetically orientated minor glyphs like the Priest's Shadowform or Shaman Arctic Wolf ones.
It helps you get on your legs when you've been ressed in combat. I think minor glyphs are made to be more or less "boring" and the paladin minor glyphs kinda goes beyond that.
