Safety?
Overdone?
Looks stupid?
What are some moves that you feel need to be used less (or not at all)?
German/Belly to Belly suplexes
Neck injuries and so much can go wrong once the wrestler is released. I remember reading someone saying they won't take Germans anymore and if you look back through history neck injuries started becoming more prevalent along with German suplexes. Same logic for Belly to Belly.
Spinning backhand/elbows
Looking at you Jericho and Kingston
These look horrible and always will. Jericho has a plethora of moves and Kingston using any old school japanese finisher would work with his character.
The dive over the ropes and onto 10 guys that fall apart like bowling pins. It's unbelievable but it's not horrible, just way overdone IMHO.
