I don't like the shortening of time. If perchance picks are made swiftly, I can find myself missing out on 2 picks if I don't have the time to check. I've done 4 or 5 drafts now, and personally, have never been more than an hour into my pick. But I still like the option of 3 hours, just in case, especially being on the corner where I can miss on 2 picks. Proxies for us at the corners are a bit more difficult, when you can find yourself 23 picks away and no access to a computer for a few hours.
What had troubled me in past drafts was when the clock was off during the weekend, and well, it was taken advantage of. I'm of the thinking that yes, everyone has outside issues, but, knowing that, should never participate in a draft if you can't check even periodically. Knowing you picked at a certain time, unless you are 23 picks away from another pick, there are few excuses for holding up a draft. If you have pick 10 or 11, or 2 or 3, surely you can proxy 4 or 5 players for your rebound pick if you find yourself unavailable for a length of time. I wouldn't expect it from someone on the end or the middle of the draft, as there are multiple picks before and after them.
