Most WWE superstars make the most of whatever gimmick they're given, even if it is doomed to flop from the start. It also isn't uncommon for certain stars to be positioned as a babyface or a heel when the individual is clearly more comfortable in the opposite role.
Braun Strowman is a prime example of someone who was booked perfectly as a monster heel yet was in desperate need of a babyface turn when he gradually got over with the audience.
Unfortunately, there are a handful of others on both the Raw and SmackDown Live rosters at the moment who could benefit from a change in character just as much. WWE might be experimenting with something new that just isn't working, or worse yet, they aren't listening to their fans and fail to realize when it's time to switch it up with those wrestlers.
Either way, the bottom line is that these superstars are suffering as a result of the company's questionable decisions, and would really shine if they weren't so miscast in their current characters.
