#2 Stop him from going after legends
Over the past couple of months, The Fiend has become a kind of a legend killer. The likes of Jerry Lawler, Kurt Angle, Mick Foley, and Kane have already faced his wrath, and this is another thing about the character we love.
The funny thing is, we love seeing The Fiend dismantle the legends and you can make that out whenever the lights go off and The Fiend is about to appear. This is a thing which should be permanently embedded in his character and he shouldn't stop coming after the legends ever.
He doesn't come after random people, instead, there is a reason for it. In Wyatt's previous The Eater of Worlds' gimmick, he came in contact with every one of the legends mentioned above and that is the reason why The Fiend attacked them.
You would have heard Wyatt saying, "In another life, they took something very dear to me," in the Firefly Fun House. That isn't a simple line; that is the very reason why The Fiend attacks some Superstars only. This is a part of his character that WWE shouldn't abandon - The Fiend should continue his infrequent attacks on WWE legends.
