The problem is that perception isn't just about accuracy... Remember how in Erathia, Spin would "bump into" wolves when they were just two meters away? And Heroist, haha, is like a ninja... with a perception of five. This is what's called, the enemies don't see you, and you don't see anything yourself. However, if in this expansion, perception doesn't affect observation and the chance of detecting non-hidden enemies, then it's fine.
