I expect them because I've played a PC game in the past decade. It's like asking why I expect my car to have a sound system. As for 'legal liability' I find that extremely hard to believe seeing as how there are literally thousands of games with a chat function.Quote from Algernone25 »A chat function opens up such a massive legal liability for wizards that I'm sure they (Or more likely Hasbro) would just rather not deal with it. Attempting to "friend" random opponents doesn't open up any way to coordinate future games, making the whole thing largely pointless. The typing in of friend codes I agree with, but again - that's ultimately a really minor thing. I'm unsure why you "expect" these from a game when they add no value to the game, and would like to understand a bit more.
Again, WotC can call it a "beta" all they want, but the fact is they are taking money in exchange for a service and right now that service is quite lacking.
