The button itself, as much as you can discuss the quality of a button, isn't too obnoxious. Let's be realistic, Blizzard was never going to have a singing dancing button with big flashing arrows pointing at it, constantly in the player's face. But this little, subtle thing in the micro-menu is just fine.
While we wait for more information, and for the store itself to appear on the PTR, rather than just that teasing button and this rather trolly UI error, WoW Insider has the things to keep you all Store-y. The WoW Insider Round Table waxed lyrical on how they'd happily pay for just about anything, the Community Blog Topic discussed what should and shouldn't be available, and we wondered whether Battle Coins could be a new in-game currency for the store. Is any of it serving to soothe your worries about the store?
