When I first played Starcraft, I was using a 1.05 CD. By that time, there were a few patches out and the game was already balanced. But I'm going to be getting Starcraft II on launch and I know it won't be balanced. I'm sure that there will be patch after patch changing around unit costs and statistics, and that's never something I've had to deal with - an evolving game on the Internet. It's going to be quite an experience, learning all the unit stats and the tech tree, and then getting upset when they nerf my favorite units by weakening their special abilities by just a couple of points or increasing the enemy faction's counter unit so that my strategies are no longer useful.

you've got a point there. I never considered that. ANd sometimes blizzard patches are soo annoying.

Wasn't there some point where they modified Lurker health to make them more vulnerable to Psi Storm? I wasn't playing when it happened, but I remember people were ticked about it and others were happy. Little things like that will mean much more if they are happening on a weekly basis.
