Bro, I went to kill mammoths 
in the valley the other night for the jc daily… complete quest and my hearth is on CD, also haven’t played since Uld so returners luck.
I goto the white polar bear quest to kill time on my hearth. Smack a few lazy miners in the domepiece and then proceed to get the mount 
Today ob my 3rd hh run, did one before reset yesterday morning, I got my hh mount.
I think since they updated the mount page in the game they might have upped some drop rates so we actually have better use for the new tool.
