I hit level 80 a while back on my Frost DK character. I've waited a bit to see if the issue would fix itself, but it looks like I'm still not receiving Emblems of Heroism when I complete my first random daily dungeon. I tried just going and buying something from the emblem vendor in Dalaran, to see if they were somehow stored elsewhere but I couldn't even buy the cheapest item after completing more than enough dungeons to afford it. I'm starting to suspect they might be disabled from RDF rewards, but I'm not sure. Can anybody help with this issue?
TL;DR: Completing my daily random dungeons but I'm not receiving any emblems.
There should be no rdf reward at current Frostmourne phase. You need to check Violet Hold for daily heroic quest. Could be changed in season 2, but might be wrong for now
Uhm, as a FM player, your case sounds kinda weird.
Like, at the start of the season, when I still had green gear, and I did rdf nm, I received the 2xEoHs at the end. Since it was rdf nm, I got those emblems only once per day. After acquiring the needed ilvl for rdf hc, I started getting both EoVs and EoHs. This should be just like the lfg system in Icecrown and Lordearon. There rdf nm also gives 2 emblems (EoTs), and then there's no reward (besides gold and XP) for that mode for the rest of the day.
I could do a rdf nm later, and see whether I'll get the 2 EoHs.
Starting the run
1st boss - no emblems for the kill (this is intended)
2nd boss - no emblems (intended)
3rd boss - you guessed it, no emblems
Final boss - 2xEoHs (daily reward for rdf nm)
Rdf nm after doing the daily dungeon - no more emblems
As you can see, this is how rdf nm should work. Did you confuse it with rdf hc? There you get 1xEoH per boss kill, and 2xEoHs at the end of every dungeon run (after already doing the first for the day).
[edit] If you are absolutely sure that you don't get any EoHs at all (even after doing the first rdf for the day), then I'd suggest writing an ingame ticket and explaining your case to a GM.
