Wow, server issues aside, it seems like this game is being exposed for being a complete disaster more and more every day.
http://www.rockpapershotgun.com/2013/03/12/simcity-server-not-necessary/It's been said that part of the reason this game needs the online connectivity is that many of these simulation calculations are made in the cloud. Apparently, according to the "insider" quoted by RPS, that is complete BS.

Apparently Sims just go to the first job they get to in the morning and the first house they get to at night. They take the shortest route. A low wealth industrial worker might be a high wealth commercial worker the next day. This completely breaks how you can design your city and explains why after about 100k-150k all hell breaks loose.
Also, apparently fire/police only can fight one problem at a time no matter how many trucks/police cars you have.

Honestly I'm at a loss at this point.
