Voslom in game economy?

[Terran]

I'd prefer if drops were kept rare and coins were used to purchase items from NPC's, potions, buffs, pets and maybe extras. With player-to-player Trading, then noobs can get kited out almost instantly.

It wouldn't be bad if it had some sort of trade limit like Runescape implemented; e.g you have to offer close to an equal value for what you're buying, and can't give stuff away.
