TWD is a tough game. No doubt about it. My LE is on factory settings. I play it more than any of my other pins, and I still haven't gotten to Terminus, Siege, Crossbow Multiball or LMS. I was close to Terminus last night. I just needed to hold the ball and time out CDC, but of course I went for more points and f**cked it up!
As far as rule tweaks, I'd like to see "20 Walker Kills" show up every once in a while as Woodbury award. It would certainly make it easier to get to LMS.
