It offered a new and unique movement system that still felt like a Call of Duty game. The was a slight learning curve so it actually took skill and made every gun fight unpredictable, it also felt AMAZING once you get the hang of it which led to some sweet kills and trick shots. I see a lot of hate for it being a "Titanfall clone" but it literally plays nothing like Titanfall. If anything, Black Ops 3 copied Titanfall's movement system exactly, and even added a "Titan-like" killstreak but I see no hate for it being a "Titanfall clone" and always see that game being highly praised.
