360 shutdown not supporting Reach customization?

I’ve heard that with Xbox 360 being shut down live, Halo: Reach armor customizations weren’t going to be supported and I wanted to know the length of that if anyone has more information.

Just how much is it not supporting? And would that also include the Legendary Edition flames that people actually paid money for? I recall it being offline supported once and not entirely sure why it’s taken online. Is that going to be made offline again or is 343 actually taking away something people paid a lot of money for?
If it was offline supported can’t that just put it back to that state?

Another question is overall customization
Would things you already have be taken away? Offline accounts can earn armor and online accounts can’t to confirm people earned them. If that’s not going to be a problem can’t they fix that as well?

Ultimately my biggest concern is the flames I paid for…
But I would like to know if there is anything more specific about this. Same concerns with Halo 4.

Hey OP, we have a number of topics about this right now. Feel free to use any of the existing topics here in General Discussion or in the Legacy halo forum
