I read it as them forcing us to fight even more monsters than before. I hope that's not the case.
Probably making it harder/impossible to skip most of the trash in CM. I look forward to seeing what they're doing with 'rewards' for trash.
I don't really enjoy doing CM over and over so I don't bother farming it, so that piece doesn't really bother me. Hopefully they don't add more trash to AK.
