I like the prospect of the dungeon system. However, upgrading is an absolute pain in the ***. First, the modal for upgrading the dungeon a single point has to be closed and re-opened to upgrade it again. It's a five step process per single point. Please allow for a batch upgrade of the dungeon where you enter the number of points to upgrade a dungeon, then the total cost is paid at once. This will really make it more clear how much these dungeon upgrades cost and increase our chances of remaining sane in our dungeons. The cost of dungeon upgrades is hilarious. I'm not sure how many points we can upgrade our dungeons by. However, I've already upgraded my dungeon by 100 points for a total of 200, if I want to add another 1000 points, it will cost me 30,500,000 gold if the IGG value continues to increase by a thousand gold per 20 upgrades. Make the upgrade dialog more usable. Please reconsider the steep gold cost of upgrading dungeons. I get that you need the gold sink, however, this makes it a fairly silly investment of time and resources and 99% of people probably won't bother upgrading and your gold sink dies in the starting gate. For the most part, the dungeon system is awesome, but vastly overpriced. Getting it fully upgraded shouldn't take 2000+ hours of game play or $1,900 of IGG purchases off the forums. I didn't report this as bug, but if you want, I'm willing to move one or both parts over. I don't see the system as broken though simply needing some tweaks.
