You have the Power, What Would You Do?
Personally I would wait till it gets even worse. And then...
I would use the Royal Rumble to start everything from scratch
All the storylines, feuds, wrestlers roles would end. All the groups/associations would die too. Not even New Day and the Wyatts would stay together. Everything would end there and the guys would be rebranded there and down the line.
And the winner of the Rumble would be Champ like when Flair won the title way back. And then you build this till Mania. You use the Rumble PPV also to start something huge, a big intercompany storyline where everything is interconnected where the pay off would be Mania. (it wouldn't end there but the WWE would have a new face/look coming out of Mania)
From Mania forward, some would have huge character changes. Everybody would be fresh. Everybody would have identified roles coming out of this.
