#3 Con - His involvement might lead to too much micromanagement

One detraction of McMahon's involvement in the developmental brand is character consistency. On many occasions, a lot of character changes, rather big or small, aren't all absolutely necessary. Some names were fine before they were changed like Mustafa Ali.
Another issue of micromanaging on the main roster that has recently affected TV is how many times scripts for a particular episode of RAW or SmackDown were ripped up by McMahon. Some were even disposed of on the same day on which the show airs. Were they really that bad that the needed to be completely reworked even while the show was going on air?

Even two weeks ago, he reportedly ripped up the script for SmackDown a few hours before the show's start time of 8 p.m. EST. While it was the go-home show before a PPV, the structure of the show and who is involved are things that should be determined well in advance. If small tweaks are needed, then make them. NXT has primarily been pre-taped so they can go back and correct any issues or add/subtract anything to the show.
Each show does have its own writing team but it has to be hard to fill up three hours of a wrestling show with meaningful segments and matches that both further storylines and feature most of the roster. NXT has seemed like its been smoothly run for most of its tenure. With the main cook in the kitchen changing multiple parts of the recipe, it will certainly change the finished product that we are used to eating.
