I was saving up for the 100,000 coin mount, but found that coins are a lot easier to get than reputation with Shao is. So now I have over 130,000 (and only half way through honored). I have enough Burdens in my bags to not need to buy any and the 496 armor tokens seem like a gamble because you can't buy specific armor slot tokens.
So, I was curious. What are you spending your coins on?
