Back when I bought DCD regularly, it was not uncommon to have breakage of joints, accessories - at least for me, your mileage may vary. But I definitely agree that the more recent waves of Arkham figures are somewhat lacking. I'm not crazy about Talia's head-sculpt, but that's a design question...however, unpainted hair isn't. Her right arm is really loose in the arm swivel, whereas my Deadshot had the opposite problem; his elbow joints wouldn't move at all until I pried them loose with an exacto blade. The paint on his head seemed sloppy, too.
Nightwing was fine, however. Didn't get Batman.
The only Mattel figure I still have on display is Two-Face, since DCD hasn't done him yet...I find the overall detailing of the DCD figures better than the Mattel ones, but the earlier figures are overall better. My Croc is still in one piece but I'm afraid to move him, based on what I've heard about his arm.
I'm still glad the line has gotten this far - if I can get one more wave with Hugo Strange and perhaps a Calendar Man, I think I can call it a day.
