Seems everyone is getting a big confused about the whole negative edge on jumping.
Everyone wants to jump over stuff and use jumping attacks. It is more on the "how" the character performs the jump that isn't liked. We want to jump, but not do constant flips during normal jumping.
Jump = awesome!
Jumping + Flip = downer
An exception is probably if you'd jump on an enemy, land on enemy shoulders, jump off and as you'd flip slash enemy head with sword. Though that isn't 'normal jumping over fence' it is more of a specialized skill to be trained in.
Jumping + attack-combo (that has a flip involved) = possibly really good.
Jumping + defense-combo (that has a flip involved) = possibly really good.
I hope this will make more sense in what I'm trying to get across.
As for WASD keys, I'm not too worried about that. I'm sure if it is really that bad, the current testers will mention it. Also I'm sure some kind of demo will come out in the coming months for a larger population to try the controls.
