New justice point question

[ElectronDF]

Here is my opinion, not fact. They are downrating frost emblems importance, since you will want new gear and it technically will be older gear. The upside is you can use some of your triumphs to help get T10 stuff. The downside is T10 will cost more then you think it will since they know you can use triumph emblems to get it. So I would buy every T10 item with frosts that you can (most expensive items first) before the switch over. Just think of triumph emblems as a head start into Cata gear. You won't want T9 gear since Cata blues are like iLVL 290+.

So my short answer, ignore triumphs and let them convert over. Work for frosts if you want, but don't worry, Cata offical date is Dec 7th, new quest items will replace T10 quickly.
