I think everyone is mostly one the same page here, correctly I might add.
Dolph Ziggler definitely should have a new finisher, the Zig Zag just doesn't seem like a legit "Finisher", it's essentially nothing but a normal bump. I think something as simple as a reverse suplex would be good for him, maybe add a bit of a spinning motion to it to make it look a bit more flashy and stall on the drop for ultimate effect. Set it up like a Twist of Fate with a kick, spin them around, and BAM! Just something more impactful. If he couldn't do it on bigger guys, that's out the window and you need a move that applies there as well. Maybe a buisaku knee kick like Kenta Kobayashi (since he's getting ripped off anyways with the GTS). Ziggler could hit that on just about anyone, off the top rope, anywhere really, and that would seem a bit more impactful.
Wade Barrett also needs something new desperately. I think he would look a lot more impressive doing the package piledriver than Kevin Steen. Just a suggestion. He needs something much more devastating than what he's currently working with that's for sure. Either that, or you just give him a straight up bad ass, never fails to impress, fucking devastating power bomb. That alone would make this guys stock (Currently at 0 for me) shoot way the fuck up.
Brodus Clay. What a waste! Here's this mammoth motherfucker, and you give him a shitty finish like a simple body splash? Is he just so incapable that you can't trust him with anything else? No, you make that son of a bitch do something memorable, fuck the dancing. I want to remember this guy because he does something almost terrible to do to someone. THIS is the guy who should be doing the Joker Driver. Look it up if you don't know what that is, it's absolutely merciless. Let this guy do that to someone, and people won't give a shit how much dancing he wants to do.
