Genau das gleiche Problem habe ich auch!!

I am having the same problem. Multi battle has been great until the update. I farm with a level 50 and a level 40 and 2 others I want to level up. The 2 max xp (for their rank) champs get removed and my 2 level 20 characters get destroyed round 1.

I have the same problem

Oh. They deleted my last comment. That's pretty pathetic. I guess you can't call Plarium out without them deleting what you say. 

Anyway, let's see if they delete this. You can only have one Max level champion in your team, and they have to be the team leader. I guess that's their way of making sure you don't farm too many resources by forcing you to use weak champs. 

Sad that this is still happening 5 weeks after being reported...

But, based a few people's responses above, it seems that this is a "feature" not a "bug"

The 3 non-leader slots will automatically remove top level champs to allow the rest to get more xp, but unfortunately this will prevent this scenario: what if you wanted to use the aura of another champ besides your farmer?  (this is what I was trying to do both times) it won't work, and would have been nice to be told this somewhere before a bunch of people wasted energy not knowing this
