Actually, I don't think that's a dumb idea at all.
If your argument is that two level 1 people would be unable to play together; first of all, you realize that after completing the tutorial, it is about 5 bot games to reach level 5. If you are incapable of playing a few bot games by yourself to get to the appropriate level, then I don't really know what to tell you. And these two friends wouldn't even have this problem, because you can type their name in. For a small period of time.
Also the number of people that would be in this situation is incredibly small.
This is a quick solution to a rather annoying trend that is getting more and more popular and has very little negative impact on the player base.
