When you hit level 27 and you think of clicking that "Promote" button, take my advice: DON'T DO IT.
I just now hit level 27 for a second time and it was an obnoxious climb back to the top (level). The stock weapons are bland, the Medical Gun doesn't unlock until level 8 (or was it 9?), the flamethrower doesn't unlock until level 13, you can't earn XP on custom maps, and StarCraft II comes out on Tuesday (it's relevant in my mind).
You are, of course, free to do with your hard-earned levels what you will. But if you're starting to burn out on the stock campaign and don't feel like playing through another 30 levels to get back your Grenade Launcher, then DON'T CLICK THAT BUTTON. Or at least don't click the "Yes" button after you click the Promote button. That's the one you really have to watch for.
EDIT: And all you get for your troubles is a silly little icon next to your name.
