Create a quickslot lock feature. It'll take you a day. Don't be cheap, or stupid about it just a simple on off switch to enable/disable moving skills on bars. It's a pain soloing inferno in chapters 1-3 and then getting to a boss without nephalem valor buffs because you accidentally dragged a skill on a bar or even clicked it. This IS a bug, anyone who says otherwise is either a prude or incompetent. Quickslot locks have been a feature since at least Ultima Online in 97. Not having one in your game is both a greivance to your paying customers and a dishonor to yourselves.
