I'm 8-0 in arena right now.  If I stop playing once I'm at 2 losses, patch comes out to make arena rewards use the Un'goro set (I assume), I lose my third game... which set will I receive as a reward?

Thanks

You will always receive rewards based on the current set, so if you wait to finish your run until after Un'goro releases, that will be Un'goro.

I'm guessing Mean Streets of Gadgetzan.

I think Un'goro 

pretty sure you get older packs. tried this last expansion heh

Under Ranges: "The guaranteed card pack given each run will always be from the most recently released expansion set. If the player earns a second card pack from the same run, they will always be from a different Standard format set."
