<t>I just snagged this game on Amazon Underground. While I haven't maxed everything yet, it appears to me that the solution is to use the online feature in the guild to fill out your ranks with the hero classes you're lacking. Have you guys tried that? My game just hangs up when I try to connect, so...

Thanks for the shout-out.

It certainly is slightly cheesy, but it's a great way to use the tools at our disposal to beat an otherwise nightmarish encounter.
