The way that announcers talk about Heels now is basically to just insult them and put them down.

It used to be about how they were coniving, bad, arrogant or whatever else, but they were still tough as nails. They still were all business in the ring and had the ability to hurt you.

Now they spend a 7 minute Sandow match talking about how much they dislike him for 7 minutes and never once talk about what actually makes him a good wrestler.

Cole used to be really bad at this and I think he got in trouble for it and had to change, although he actually did it for faces since he was the heel commentator. I feel like they forget how much the announcers can shape how we view the match and the people in it.
