Which Hasbro Molds Should Return to the Retro Line?

All of them, the retro line should replicate each of the Hasbro molds, there should be no more molds, no new molds

And there were more jumpers in the Hasbro line than the Retro line

They should use the suplex move that Mr Perfect had had and the wind up punch that Bret Hart had too. 
Id like to see them use the slam that Lesnar has more often as well as the reigns punch.
I know I'm in the minority here, but I like the jumper move, they have just used it too many times already. If they cooled it for a while, I'd be happy to see it used again down the line.
As for the Rick Rude move, I hate it. However, there are so many skinny sawed off runts in wrestling today, I could understand why they'd want to use it for a current guy. 

I'd love to see the suplex from hogan 3, mr perfect, and crush. might get me interested if they use more than jumpers and press slams

My last Kmart never had him & now they’re closed. I’ll pay retail plus shipping if you grab me one with a nice bubble & card. I’m MOC...

I think you mean, action move. As the molds don't exist anymore or are owned by Hasbro.

They should use more of the virgil punch, they only used it once in S1. I wish they would cut back on the jumper and it looks like that's happening based on the next few sets coming. But, I also want that awful split torso mold to go away. Same with any of the guys with the bo-legged look like Macho and Angle.

I always liked the Tornado style move. Would look good for a Bulldog retro.

The only mold I truly despise is the Cena mold. It's overly buff for most guys and the action feature is too specific to Cena. It ruined Warrior. He should have had Brock's feature.

Like some others, I just came in here to say: all of them 

More precisely my top choices would be: the Perfect-Plex move, the elbow smash and the upper-cut (Smash, Brutus 2, Nailz, Bret Hart, etc. type move), with honourable mention to the Tornado punch also - I liked that a lot.

Of the moves that the Retros have already used, then the Brock and Roman moves definitely should’ve re-appeared by now on someone given the recycling required by the rather limited budget of the line. I actually don’t mind the jumpers, but it has just appeared too often so far - replace the Goldberg one with Brock’s body with matching legs and things would look better on that score I think.

I’m all for new moves as well if Mattel want to try new things - the Hasbro moves are 25 years old so some new ideas may be possible now that weren’t around back then.

But that said, the only move I don’t like is the Cena action - I applaud Mattel for trying something new, but I just don’t like the split torso look. If they could’ve worked the move without the split torso then I’d like it more, but as things stand I’d retire that one and move forward adding new figures with Roman and Brock actions, with a “new” classic Hasbro move going forward as the far as the budget allows.
