So I raided alot in WOTLK but afterwards I had to clean up bank and deleted my T10 heroic, its retarded but back then there was no sign of Transmog yet and I had no space left at all.
Now I want it back, and I obviously can't item retrieve it anymore, yes I tried, also with tickets but as I expected they can't go that far back.

Is there a way to get it back by farming, because the T10 point gear required emblems of heroism etc...
Also would I have to farm both normal an heroic again to get to the heroic version as it "upgrades" itself all the time.

I am a protection warrior, itemelvel 478 right now, just came back from a 5 month break so trying to get some nice transmogs going and I LOVED T10.

Thanks in advance.
