The only one that's really that "swingy" is the Flooded Areas from the expansion, and it's easy enough to just remove them from the pool if their impact isn't for your particular group.And all but the expansion ones are on the back of the Neutral Unit cards, so rules lookup doesn't take long (and if you remove Flooded Areas, the only expansion one left is the Defensible areas, which aren't a big deal).
Granted, some people like them, some don't, but I like the little nuances that they add to the game.
