If I get the chance I'll go back and give some specific feedback about the specific limitations that gave me problems and why.
At the moment, I don't have the luxury of being able to open the Foundry to review and I don't recall exact details because I'm a little sleep deprived
Some of it was various components that you can trigger to become visible, but can't trigger again back to hidden. Some of it was not having the full range of triggers available on every component. Some of it was not remembering what I had to do to make optional interactions on components. Some dialogs I couldn't set to fail. Fun and games with Reach Markers I thought would work as the triggers I needed, but didn't and finally ended up taking out as unnecessary.
The ability to trigger state on objective/component failure would be nice, too.
Oh, and slightly off topic... why the heck don't nav beacons show up on the map during mouse-over with their given names instead of 'nav beacon'?
