To be frank, I never even knew they were there to begin with until it was pointed out in this thread a few days ago. Now that I know they are there, I prefer not knowing they were there because I do concur that they are a bit dumb. Even though them not being on the figure is technically an inaccuracy, it's one inaccuracy I'm actually glad they didn't get accurate.
As was mentioned, I'm not going to be displaying the figure backwards anyway, so I couldn't care less if they were there or not. It's not really that big of a detail to me. It was mentioned before that the spikes were apparently on the CK version, but the CK version lacked the scarring on the right shoulder. Between the two, the scarring on the shoulder is a detail I'd rather have every day of the week and twice on Sunday.
