Chances are that YOUR Wolverine has his elbow cut off if your balls aren't getting stuck. Do you think Stern said "OK...lets design a Wolverine figure and make it so the balls get stuck under his arm. We will release the first ones like that...then we will start cutting the elbows off of them so the balls won't get trapped."? No...it was designed poorly and they had to cut the elbows off to FIX the design flaw.
Also, as I stated above, if you upgrade the light in Wolverines head and it is ever incorporated in the game. You will see the light shining out of his new elbow hole brighter than through his plastic head.
Keep in mind that I have never had a ball get stuck on Wolverine either. My Wolverine has his elbow cut off. It isn't noticeable or an eye sore, but I'm not going to stick my head in the sand and pretend that it wasn't a design mistake....because it was.
As far as the claw issues go...It sounded like many had to do this "adjustment" to keep Wolverine out of the ramp. Mine still touches the ramp when it starts to make it's return visit, but it doesn't effect anything. People have posted that their Wolverine figures even had multiple holes put in the back of him from where they tried to mount and remount him to get him out of the ramp. Wouldn't having his arm not pointed directly at the ramp have prevented this? Sure it would have, but it was designed poorly.
This figure was custom made for the game....why should there be ANY issues with it? If you feel the need to justify your purchase by pretending that everything is as perfect as it can be...go right ahead, but it's pretty hard to argue that the figure was poorly designed when they had to grind part of it off to make it work.
