OP is right tho, if the WWE title is really a wrestlers dream then ambition to gain it should tear the New day apart, plus they have to break up at some point rather then riding this shyt till it completely breaks down.
I was always against a Kofi Kingston title reign because i couldn't think of one single feud or angle i would be excited to see concerning Kofi and the title but the New day implosion would actually be one. Its an easy story to sell too, Vince tried to keep Kofi out the title picture and stop him becoming champion but failed thanks in part to New days support, it was them who helped Kofi get the match, so Vinces next logical step would be to take that support away. Vince should start planting seeds of discord in the New day, tryna convince Big E he is more championship worthy and tease tension between Big E and Kofi but ultimately have Xavier Woods turn heel on both of them, its the least expected heel turn out the three and i think Woods would deliver better heel promos than Big E. Have it culminate in a Triple Threat match for the title.
I'd either have Woods turn heel or Kofi turn heel and dump both of them.
At this point, Kofi is bigger than the New Day. Kofi sticking with New Day makes it seem like the real WWE champion is New Day, not Kofi Kingston. Plus a split up could potentially lead to a Big E WWE title run.
