Agreed Jkno and I don't like the idea that he gets injured again. I want him to seem like an untouchable, unstoppable force. I notice there seems to be a tendency lately to do this weird "battledamaged striptease" with Vader where his life support suit and helmet get damaged and ripped away during fights in some of the other material (namely The Force Unleashed and Rebels) and I always found that to be really dumb. Thankfully TFU is no longer canon but unfortunately Rebels is. Nevertheless, I don't want to see RO continue the trend.
See that doesn't bother me in the least.
Well it makes his suit seem oddly flimsy and with the emphasis that the suit is a self-contained, sealed life-support apparatus, he seems to be depicted doing pretty well even when it's torn to shreds. Makes no sense.
If they do show Vader unmasked I would welcome Hayden back with open arms.
