We understand that players are eager for patch 1.0.5 to go live: we are too. Testing is well underway for it, and there’s a lot of great stuff coming just around the corner, including the Infernal Machine Event and the advent of the Monster Power System.
The best possible thing you can do to help us progress is to [url="http://us.battle.net/d3/en/forum/topic/6678687803"]join in on the PTR[/url], offer your [url="http://us.battle.net/d3/en/forum/7328695/"]constructive feedback[/url], and submit [url="http://us.battle.net/d3/en/forum/7328696/"]detailed bug reports[/url] about any issues you may experience while playing on the test realm. These reports are incredibly valuable to us, and we greatly appreciate those of you that have taken time to play on the PTR and offer us your ongoing feedback and bug reports.
I'd love to test the infernal machine more, but farming keys for several hours to try it isn't worthwhile. If those summoning devices were available at a vendor, I'd help out and test the Uberbosses.
Now I've done the bosses a couple of times and can't find the motivation to farm keys.
