from Jeff himself:
Hi all,
We’re making a change on our PTR servers shortly (no patch required!), that reworks some of how our heroes move and accelerate.
This was originally done to fix bugs on a couple heroes, but the changes are systemic and affect all Heroes.
Specifically, movement on the ground is much more consistent. Going up/down inclines will no longer affect the Hero’s speed. Previously, inclines could either make you move slightly faster or slightly slower, depending on the circumstances. Inclines will also no longer cause a small amount of strafing movement when moving diagonally on them. A side effect of these changes is characters will now have slightly better air control. For example, Winston previously was not able to easily make small adjustments to his flight path during his Jump Pack leap, but now he should be able to do that, and it is also noticeable on many of the other Heroes that are often in the air.
We think these changes will overall be great improvements but there might be some unintended side effects that we’d love your help finding on the PTR!
Thanks!
I went and fooled around a little bit and the changes are HUGE for Winston, so much more control in the air and you can strafe WAY further to the left and right while in the air
