Inflation isn't a big deal on Nost -- yet.
The only significant problems in the economy are the prices of black lotus/plaguebloom, which doesn't have much to do with inflation.
That said, additional gold sinks would always be welcome. It's smart design -- as early as Wrath you started seeing high-price vanity items sold to destroy gold. I'd pay out a heavy fine for a panda pet, a mini-diablo, a tabard of frost, or any other number of the vanity items available.
