I think the whole "most of this is now automatic" things regarding freerunning first added in AC3 and refined in AC4 and Rogue took some getting used to, but was easy and intuitive, despite what I've read about people "running up walls" and shit. Never happened when you got the feel for controls and how close you could run to walls to actually run up them instead of keep going forward. If you still failed, I'd question your mental capacity.

Now in Unity, it's a goddamn crab-battle 90% of the time. I see the things people complained in the above games -here-, instead.
