When I stop pressing forward it's because I want my character to stop, not to take a few more steps to slow down (especially if I'm trying to dodge an AOE or cast). The problem with inertia and weighted animations is they sacrifice responsive gameplay for something that looks nice. Even Yoshi-P agreed 1.0 was too focused on looking nice and not enough on being fun to play; this is one perfect example of that. Coming to an instant stop can be immersion breaking, but it's far worse if you don't have full control of your character simply because it looked pretty.
