I made a suggestion to Blizz on their forum I'd thought I'd share here. If you like this and want Blizz to see/impliment it I'll post the link to the forum at the end so the post can stay current with replies/support.
Dear Blizzard:
I appreciate your recent change to the price of Mogu Runes of Fate costing only 50 Lesser Charms of Good Fortune. It allows a casual player who can only play 1-2 days a week to get their bonus rolls. Nice work.
But there is a problem. What about we every day players who collect lots of Lesser Charms? Currently I have enough charms to last me until sometime around October 24, 2014! Yes, I have 4238 Lesser Charms! We need another place we can spend our Lesser Charms, and I have the perfect solution.
How about letting us convert Flawless <Family> Battle Stones? Here's how it could work.
Make a daily quest that costs 50 Lesser Charms (or whatever amount you like) to convert 1 Flawless <Family> Battle Stone into a random battle stone of another family? I know how you folks at Blizzard love your randomness! It might convert to any other family except the one you started with. So if I converted one of my 3 useless undead battle stones I would get something else, but never an undead one. This helps players unload extra Lesser Charms and at the same time helps with getting that last specific family battle stone you so desperately need.
Also, you can NEVER get a general Flawless Battle Stone this way, only a Flawless <Family> Battle Stone. All stones remain soulbound.
I don't see a downside here. Making it a daily quest means you can only convert a certain number of stones per week/month/etc. and making the conversion random means I could spend a month trying to get that one family type I might need. Also, this should be relatively easy to implement. Certainly more so than your current change to make unlucky streaks on drops less prevalent.
The need for this is real. I hope you agree with me and find a way to implement this.
Signed;
A daily player of WoW.
