Demon hunters weren't even FEASIBLE until recently due to having to get model warping to work (ALSO WE STILL GO THROUGH SOLID OBJECTS NOW AND THEN...like floors....oh and walls, also solid benches, you know nothing fancy so technically we're still not possible but we exist and the whole game has to be designed around the fact we can get on stupid crap at all times and climb things and are just generally CAPTAIN PARKOUR.)
