#2 WWE Must retain their current talent
In addition to developing new pro wrestling talents, WWE must also take care that they are able to retain their current crop of superstars.
Once someone has performed with WWE, they have a great deal of recognition in the pro wrestling community, even if they never made it out of the lower part of the card. This means that the former WWE wrestlers can find employment most of the time, even if it's on the independent circuit.
In order to prevent AEW from acquiring even more talent than their already stacked roster holds, WWE must try to keep its current superstars happy enough to remain with the company. The WWE has done a good job of this with the Revival, who originally requested their release because of a lack of focus on the tag team division. Now that the WWE has made some changes, the Revival seem to be happier with their position in the company.
WWE needs to keep its current talent pool happy if they want to stay relevant against AEW.
