I guess it's not too much of a surprise given that this is an Ubi game, but Easy on this game is labeled "Normal," and Normal is labeled "Hard."
True. To be honest, I went with Hard on my play through, on GAF's advice, and man am I glad I did. The game really wasn't that difficult at all, even on Hard. Granted I did grind a fair bit, but I still only died a handful of times, usually just out of complacency or a lack of finding the right tactical flow.
