This is getting ridiculous. Kabam keeps putting up these "Buy 100 rubies and receive a prize" offers, but their prices are so high no one wants to buy them. If they really want people to buy their stuff, then they should lower the prices. 400 rubies for 499 kreds... That's a full $50 you're spending for something that may not even be enough to get what you want (so please + this so dev. can see.)
Developer should give the option of assigning hotkeys to tier 4 abilities. It gets pretty annoying having to click on the icon when you've got multiple dartling guns.
Yeah, we'll fix that eventually. Sorry for the inconvenience.
