Look at the alignment issue, it's a simple issue:
There are 6 US teams in the PST or MST: San Jose, Anaheim, LA, Arizona, Vegas, and Colorado.
That leaves room for 2 more.
US teams in the CST: Chicago, Nashville, Dallas, St Louis, Minnesota.
The 'problem' here is that Chicago and Nashville will obviously temporarily align with an EST-based division, based on Geography, and no one would complain about that.
But, that leaves Dallas, St Louis and Minnesota. All 3 of those would prefer to be "east" rather than "west". So, someone is going to get the lucky draw. The first draft had Minnesota with the lucky draw, but of course Dallas would complain about that. (Minnesota would have if it went the other way, too).
Some suggested doing a 4 x 6 for 6 US divisions. That sounds good, except then you get the issue the other way. There are exactly 11 US teams in the PST, MST, CST. 11 isn't 12, so some EST team has to play in the CST division, and then they would complain.
Nothing perfect about any solution here.
