I've always thought that figures with exposed wrists and ankles should have an optional replacement part that has no seam and no articulation. You could choose the jointed version for poses that require it, or choose the seamless version for greater realism. Hell, they already include a ton of accessories with most figures, it wouldn't add much to the cost to include an extra pair of forearms.
i hate extra parts.
every time i have extra parts, i get some parts to build another figure around them, until i'm out of parts.
then i get some extra parts to keep just in case i break something... it's a vicious cycle.
