Indeed, I don't think upping points to 2000 will balance stuff. It just adds more one-trick lists to the list of evil. On Dakka they keep going on about zilla nids, drop pod termies etc. To take the IW further, it then definitely allows you the full 9 oblits, the 4 heavies, the second infiltrating speed HQ and some infiltrating las/dual/plasma whatever squads to really go to town. Not to mention how evil Necrons get at higher points.
