Yeah, that was the exact way it worked at Cata - every new patch has seen “lower” emblems (justice points at that time) turn into gold (around 2:1 ratio - you basically took your JP and divided them by 2. This must be different with emblems though, you had up to 4 000 JP and gathered them by 60 iirc, EoH work much differently) and “higher” emblems (valor points) turn into justice in 1:1 ratio (this could well remain the same).
I’ve got one question though: where did they announce / say that WotLK classic will work this way? Up to this point, I was under the impression that there will be usual WotLK emblems - conquest, triumph and frost, in this order.
Thanks
