#2 Losing continuously in front of thousands of people

The Revival is a great example to prove this point. Their NXT run was much better than their current main roster run. This team lost multiple matches in recent times which only hurt them. After losing on Monday Night Raw, a few weeks ago, Scott Dawson and Dash Wilder finally asked for their release. However, the WWE rejected their request.
We can easily relate this point to other top superstars in the WWE who were once at the peak of their career but now, are nowhere near it sadly.
Once, Ambrose was also one of the most popular superstars in the WWE but the last few years have not been kind to him at all. The same could be said for some mid-card superstars who may also decide to leave the company soon.
