It's a nice figure, and a great representation of Warpath, but I think you've got rose colored glasses on.
Warpath is missing a few bits of articulation that IMHO all masterpiece figures should have, wrist swivel, waist swivel, ankle tilt, and the range of articulation on his hips is limited. His head is on a swivel that doesn't let it move up or down.
The presence of these limitations doesn't mean it's not a good figure. It just means it's got a ways to go to be a masterpiece. As a Generations style representation of a G1 character, it's a solid addition to any collection. And who knows maybe HasTak will down the road base a masterpiece figure on this representation, which wouldn't be bad at all.
Cheers.
