I'm convinced that the biggest reason people don't like Legacy is because some of the keys are flipped compared to Standard. If you switch to Legacy but change the offending keybinds, the controls work just like Standard except your camera doesn't continually snap whenever you move.
Keys bound to Move Left / Move Right in Standard: bind those keys to Point Camera to the Left / Point Camera to the Right in Legacy.
Keys bound to Strafe Left / Strafe Right in Standard: bind those keys to Move Left / Move Right in Legacy. Leave Strafe unbound.
In Legacy movement settings: Disable camera pivot.
This will give you "Standard, but the camera doesn't snap to character every time you move." It does however, disable turning in place--which is a separate problem which really should be solved by the devs making right click turn in place even when on Legacy.
