- Sami Zayn ditching El Generico for a new character in NXT is reasonable, but it could've been done on the main roster. I'll give you that argument though.
- Nakamura didn't need to learn English in NXT
He was fluent in English before even coming to the WWE. He knew the rules of TV and how to engage the American audience because his gimmick was entirely built on that. He had no business being in NXT and no business being in NXT for as long as he was.
- The independents aren't the same as they were 15-20 years ago. These guys have been traveling all over the country and world prior to the WWE. ROH/Impact/NJPW were in the cards for almost all of the guys they signed. They didn't need to get use to the travel (NXT doesn't even travel like the main roster does). The culture in NXT is drastically different from the main roster according to a lot of guys too, so I don't really buy that.
- Guys like Elias and Braun all survived in spite of NXT. They were thrown in the deep end on the main roster because they were floundering in developmental. Lucky for them, their talent brought them to the top.
- Apollo could've used more time in NXT to polish off his promos and his character overall. This was another one of those sink or swim moments, and he unfortunately sunk. He wasn't ready for the roster, but they had to move him because of all the Indy wrestlers they keep signing.
- Joe/Balor/KO didn't need to be in NXT, and NXT doesn't deserve any praises for their main roster success. They basically just bided their time to get called up. The jury is still out on Baron Corbin. I see potential in him, but he hasn't broken out yet.
