Having played several rounds with uneven lies on now, I think the amount of correction one must make in setting the aiming point is absurdly large for most sidehill shots. Likewise, even a slight uphill or down hill lie seems to take huge chunks of yardage off the shot distance rather than the subtle difference one experiences in real golf.
I wish it worked well because it adds another element of realism into an already excellent game, but only if they get it right. Currently, it's pretty ridiculous.
