She was hated backstage. Probably the most disliked WWE wrestler to work with.
From watching interviews, a lot of people stated she had arrogance about her and how she thought she was hot shit and deserved more pay. The male wrestlers hated working with her and they felt they had to carry her during matches.
I believe her arrogance is the reason she was canned and not because of HHH and Stephanie. Not to mention, she had a host of mental problems which HHH probably saw in real life. I believe he made the correct decision to go with Stephanie given how crazy Chyna was in real life.
