Have u consider a possibility that GE already did so many offer to those players u mentioned but they refused to play on GE.
Maybe GE just want to rebuild like EG roster. Just a combination of some average players but with a great coach team and structure , they can built a great team eventually.
I personally doesnt know who better duelists out there that better than polvi, available to be bought, and also willing to move across country to compete. So im fine with polvi tbh.
