#2 EC3

Just like Robert Roode, EC3 was too pushed to the main roster from NXT very quickly. He made his NXT debut in January 2018 and in December the same year, it was announced that he would be debuting on the main roster.
It looked like Dean Ambrose, who was on his way out, was going to put EC3 over and then leave the company. The two were in a feud for a short time but it ended abruptly. EC3 is caught in the middle of nowhere and is seen on WWE TV running around, chasing the 24/7 title.
Triple H could have done a lot more with him in NXT and EC3 would have been a brilliant NXT champion as well. it is unclear as to who made the decision of bringing him up the main roster so soon but it's very clear that Vince is not in favor of giving him a push any time soon.
