It is a great idea. If blizzard uses this it could be alot of fun for all starcraft players good or bad! I mean if you keep losing in the sc game you shouldnt be getting a high rank, you should be losing rank... so I think the campaigns should have there difficulty based on your rank!! That way if you suck, the levels will be designed for someone that sucks to get an easier level. and to keep getting easier until they can finally get the hang of it. with that said... I am a pro so the levels should get harder and harder for me from the start.
