#5 Braun Strowman

In all honesty, the career of Braun Strowman is probably too far gone for any major changes to his gimmick to take place. Whether it was intended or not, the WWE Universe has really gotten behind "The Monster Amongst Men" and given that he is about to face Brock Lesnar this Sunday at No Mercy, he seems pretty well established amidst the main event scene on RAW.
That being said, Braun Strowman, when you really examine it, is a terrible name for a superstar, especially in 2017. It is less of a name and more of a pun - 'braun', similar to the English word 'brawn' meaning strength, and 'strowman' which is a slight variation of 'strongman'. He is effectively called strong strongman, which is something a 6-year-old child would probably come up with for a wrestling name.
Some fans might not know that Braun was actually a professional 'strongman' before entering pro wrestling. But if anything, this makes the whole thing even worse. It's like the company were so unimaginative that they just named the guy after what he used to do.
There were, of course, many other examples back in the early 90s of characters being named after professions - Repo Man, The Mountie etc. but I don't think many of us are calling for those days to come back.
It might not be too late for things to change. After all, two of the company's biggest ever performers went through a slight change of name when Rocky Maivia became The Rock, and Hunter Hearst Helmsley became Triple H. Both of these adjustments happened while they were already established in the main roster.
