Downvoting should be removed. It's basically a popularity contest where people downvote others just because they disagree, not because the comment itself was bad. I don't necessarily mind sorting comments by how many votes they've received, but when it's essentially a popularity system, it doesn't make much sense to hide the comments that aren't popular enouh. It's essentially hiding unpopular comments even when they're good, and I don't think hiding any good comments is good for discussion.
