ZEITGEIST 5E Battlemaster, ZG Polyhistor ?!?!?!


I hadn't read the Polyhistor paragon/prestige class until now. Wow.

It has martial dice, that you expend to perform special attacks or defenses, and often add the result to the attack or damage roll. Designed during D&D 4E.

How is it possible that absolutely no one has ever commented on the similarities of the 5E Fighter Battlemaster, with its martial superiority dice and strikes? https://www.google.com/search?q="zeitgeist"+"polyhistor"+"battlemaster"

Did someone at WotC get the idea from Ryan, or did both ZG and 5E get the idea from some earlier source?
