They seem to heavily rely on table spots for big beatdowns nowadays. Back chair shots look 100x dumber on Roman because of his stupid vest thing though, even if they really go at him.
I guess its what all the wrestling pundits and ex-wrestlers say about stuff like that or Hell in a Cell or any sort of stip match nowadays - it doesn't work when you can't reallyhit a dude with a chair or bleed. Speaking from a position of ignorance, I would say blood, whether capsule or blade would be the healthier of the two things to bring back. Look at how it upped the intensity of the Balor/Joe match. Those two are probably going to have a cage match next and it'll be as clean as a whistle and won't live up to the opening moments of the Dallas match and STILL be as hard on their bodies if not more so. Hell, I can still remember my deep disappointment at the Bull Dempsey/Baron Corbin no DQ match, which had been built for months as a conclusive blowoff to a heated feud between two monsters who squashed dudes in seconds. Instead we got some lame ass soft 7 minute fuckery with a single super weak chair jab. Booo!
Then again, like Data points out a lot, Shane at Mania, Kalisto nearly dying at Payback, reverse ranas, Sami's exploder on the ladder to KO, the existence of Dean Ambrose are all acceptable but a piledriver - a relatively common and safe move is banned? The rules are in flux right now post DBry. We are on the precipice of some very disruptive CTE testing getting online that will probably change everything. When they start finding high schoolers with it, swimming is going to become the only acceptable sport to watch and not feel horrible guilt. So even that twinge of "man I really wish he'd just smack him in the head with the chair" is going to be something you'll have to relegate to "will never ever fucking happen again".
Unless it's Taker and Brock.
