Here's a tip that blew my mind: you don't need to collect all pivots to be able to activate them. For some absurd reason the pivot activation menu is hidden in the options menu of the pause menu, whereas everything else regarding pivots is a submenu of the map. Makes little sense.
But anyway, by some absurd struck of luck I only have the Tao Pivot which was exactly the one I wanted. So I switch to wintertime, run through the trees, hear a drum in the distance, move towards it and arrive just in time to see the patrol get attacked by a bobcat. They take it down, and while they are still recovering I jump to a branch above them, target the biggest guy in the group and string him up with my rope dart.
Before the rest even knew what was going on I was slicing through them with my tomahawk, all amidst a winter blizzard while dark red blood fell on the white snow.
See, this little moment right here? That was the coolest thing I've done so far in the entire game. THIS is why I bought this game. This is awesome.
Edit: god damnit I thought those were real patchnotes a few posts above mine. My heart skipped a beat at the "return the hood". Fuck.
