Borussia Dortmund will continue to fight, but I see they will not be able to beat Bayern Munich for now. They will remain under Bayern Munich. As for the Champions League competition, it will still be more interesting than the struggle for the Bundesliga title. I'd rather see in that position than see positions one and two.
The level of the Champions League with the Bundesliga is clearly very much different, bro, because everyone who likes football definitely likes the Champions League and they also don't necessarily like the Bundesliga, although they occasionally watch it when big club matches like Bayern Munich are playing. And it's true as you said that the BundesLiga is now less attractive and it's also very easy to predict who will win the most matches so the fun seems to have just disappeared.
