That is all bullshit. The Awlpike has one purpose on the battlefield. Kill. Plated. Shit. Shouldn't it make sense to have it be exceptional at this one task, considering it is so flawed in many other ways?
As you already covered in your post:
It's a support weapon. When used properly as a support weapon it becomes far more effective than most other weapons used in combination. Two moderately skilled players, one with a 2h sword and the other hoplite-ing with an awlpike, can charge archers, using the awlpikeman's shield, kill cavalry, using the awlpike to disable the horse and the 2h to finish the rider, kill most players in under three seconds ((1) stab+slash or (2) 2h-slash to distract then pokestun to get guaranteed damage and to setup a second slash), and effectively disable every single crushthrough weapon. I find the awlpike very potent and not in need of a buff.
The long awlpike, on the other hand...
