If it doesn't affect the divisions, or if there is an easy way of re-configuring the divisions involving two teams or so, then relocation is all good. Again with expansion, if the league plans on keeping the 4 divisions for the time being then fair play, make it an even number for both conferences to maintain equality. My only hope is it doesn't exceed more than 32. Don't get me wrong, I love the English tiered system for soccer because of the excitement in April (Sheffield Wednesday usually in the mix of it!) but NHL should keep the league status by keeping an eye on the amount of teams playing, could easily get carries away with adding teams.
