So, in melee if you're hit by a move and then tech, your momentum is carried into the tech roll. Look at this example here: https://youtu.be/INAphSex3z4?t=13What's the difference between how PM handles tech rolls vs melee's way of handling tech rolls? Are PM character's tech rolls just kind of ****ty?
Roy was sent back by marths fsmash but tech rolled forward, as a result the momentum carried into the tech roll forward and he didn't roll as far. Currently in PM, the tech roll would not have been affected in the same way, It would have instead went its regular tech roll distance. This is very relevant in tech chasing, because if a throw sends you a far distance away and you tech roll away, your momentum in melee would add onto your tech roll. In Project M, it doesn't so its always a fixed distance to easily punish on reaction.
