I think those are great ideas. Think about the most memorable moments from the 80s and 90s. Those great Piper Pit segments were never more than 5 minutes. Go back to any of the old TV until the Monday Night Wars. It was a very snappy presentation that kept things moving along. I also think talent rotation is a great idea. They have a big enough roster that guys can take a couple of months off here and there. It gives you returns to surprise the crowds with here and there as well.
I think a 10 episode "season" might be an interesting concept to try. Build your storylines for those 10 weeks, blow it off at a PPV and then take the losers off of TV for a bit and move the winners on to the next thing.
I would also unify the World Titles, the Tag Titles and the Women's Titles to cut down on the belts running around right now. I think having a World, Tag, US, IC, Women's, Women's Tag and a Cruiserweight belt are probably too much but better than what we've been dealing with. But I think they need to go back to the belts having defined levels. It just feels like they throw the belts on whoever and it's ultimately meaningless.
