Just did this quest "Hides for Brianna" out of thundermist village. Had to get 15 Rumbler hides (found them down on the south west tip of TS on the beach by Boulderboom) Theres a small cave there and it took me about 20 mins or so to get them. Ran back and handed them in and got a full orange bub of xp at 23 and the choice of some pretty cool boots. Plus the xp from rumblers (orange to me, think they were 25-26 ish). So all in all i reckon you could do this in 45 minutes round trip for some good xp and a nice reward. Couldnt find it on the Ally's quest list so thought id post it.
