I think most noticeable flaw in any team I could think of is with Toronto and specially with their location. As huge hockey market it makes sense to have team there but here it doesn't give them any advantages, no extra marketing or media spotlight, but what they get instead is division with 3 other teams that are all good enough to compete for cup and president's trophy if, at least with some luck. This gets us to point where either some of these top teams needs to take a quite hit in near future or Toronto needs to push to be top 4 team in league to make it into playoffs.

I have talked about reseeding divisions based on performance after every season but that didn't get anywhere, who needs more fair competition anyway. So as that option is off the table I think Toronto should relocate as far from Great lakes that is possible, though still staying in North America as if they go to too odd location it wont fit anywhere and keeping them in same division makes as much sense as adding them to any other.

San Diego North Stars sounds pretty good to me and should get the problems fixed.
