There had been a trend over the last few events to remove roads in an effort to make it easier to tap creatures. This was well intended, but I think some people may have overdone it. There are several level 59 towns whose entire group of characters collect on one tiny strip of roadway, making it impossible to single out anything at all to tap. This drives me nuts. Plus, it doesn't seem to be working for this event since the gamblers do not seem to be drawn to the roads. I still have to scroll all over looking for them.
The lack of roads can tend to make towns look messy. But then there are people who have towns that I refer to as "organized messes" - they basically stack all of their buildings one against the other with no spaces. It's also hard to tap individual things here, plus I have absolutely no idea where to find the gamblers.
