I honestly can't disagree more. I just played two matches and by the second match I was again flying through the map like this (sorry for the black bars):
I kept reading about how much slower and more sluggish TF2 was supposed to be compared to the first game and I don't understand where that notion is coming from. I was jumping and wallrunning around like during my best TF1 days and was rewarded for it with an end score of 26 to 12, picking off the guys just sprinting around, playing it like CoD, just like it was supposed to be.
I know "This is just X version of CoD" is a very popular and easy thing to say, but having the movement in this game is so, so much more elaborate, useful and fun than in AW or BO3 (even though I haven't played BO3 too much - the best players make the movement look like TF, but I have never gotten into the groove myself).
