I more or less feel the same way. I get taking away big names from AEW when they can, but I'll be more interested when they can get someone who hasn't been in WWE before--Jade Cargill and Lexis King, for example, though the former hasn't debuted and the latter is an NXT guy so it's not quite the same.
As for WrestleMania, yeah I'd be surprised if it isn't Punk/Rollins, but I'd prefer they do that sooner and convince Steve Austin to come back for Mania. He took back bumps on the floor two years ago and discussed a match with Brock this year, who's to say he wouldn't come back for another big payday match?
