Yeah it really is a shame, teams seem to only be able to compete for a few seasons with Bayern before the inevitable drop off, be it Dortmund now or Leverkusen, Schalke and Bremen in the past.
If you are looking for a team to support check out this website for a fun chart. A few years old but still good.

Also if watching the games is not enough check out the excellent Talking Fußball podcast. Really well done show by a few english guys. You can listen either on the website
http://talkingfussball.com or by downloading episodes on iTunes. I highly recommend it.
On another note, I don't know if people are interested but I can add usernames beside the team symbols on the first post if people are wanting to see allegiances. Let me know.
