If anything, it would be nice to be able to transfer valor stones to alt characters. ATM after I finish my main 7 characters who regularly sit at cap and just do the content even after hitting cap, my lesser played characters could use more stones.
On average I play about 4 of them a week after I grind out my weekly content and generate around 150-200k gold across my characters a week just questing. I’m currently now in the process of making my other 31 characters gear current season 2 minimum base of 626 max of 636. This opens up the cosmetic of LFR / Normal and my main 7 open up the Heroic and sometimes Mythic level of cosmetics.
