Having played for a bit and generally having fun I started poking around in the store checking it out particularly in the Currencies section and see Chests of Gold for sale. The chests are there to combat gold farmers maybe? That's really the only item I'm not fond of in the shop due in part to how it could potentially effect the economy, escalating prices, market control etc.. Other than that I feel the shop is mostly fair.
Searching through forum posts I've seen a dev remark on removing it during beta but I'm guessing that didn't go through.
Even though I find the game fun my interest plummeted after seeing that in the shop. I doubt I will continue to play but I hope your game and community thrive.
