I really wish to see some competition in the Bundesliga but I know that I'm just deceiving myself on one hand. 
Because this has been the same for 10 seasons and it is likely to be another 10-year time period now. As long as we don't see any other team (except Dortmund) being bought by a billionaire, there is no hope for a new challenger to come out and fight with Bayern Munich hard for the league title. I'm really frustrated with Dortmund actually about this topic. They have such an amazing potential as they are a rich team. But just this business model is killing all the fun we could have.
