Back Paddling is horrible.

[Majidah]

when not fighting?I turn my direction, what is the problem here?

Exactly. So if most of the time you aren't fighting, and when you aren't fighting you turn your direction,

its very clear that it's more natural to turn by default and to back pedal only under certain circumstances (ergo: target or an extra button). Currently in 2.0 you ALWAYS pedal back when pressing back, and in order to turn around you need to press an extra button.
