Sorry, but it's really hard to trust them when they cut major design features this close to release, not that the single player thing effects me, but hopefully you see where I'm going...
On the flip side, maybe they deserve a bit more trust because they're willing to make a hard decision at a critical time that allows them to focus on the part of the game that does affect you (and I'm assuming, the majority of players) for the betterment of the game. Bad news is bad news whenever it's delivered.
