They didn't do it in less than a week either, though. It took them 2 months. A whole patch.
Joveth can't hit any buttons to lower the cost for us, and looking at the past history of things going on in this game, the repairs could in fact be higher than they intended for reasons they weren't aware of.
Yes, but lesson learned by Blizzard and yet EA/BW wants to experience it themselves?
Besides, someone in the CS forums already said the repair costs are WAI. So the only thing left to investigate is "Should BW reduce repair costs or not?"
