i definitely agree with you - astralis is ready for a roster change. but they will absolutely stay fully danish. theres no reason to bring in a swede and brazilian (both of which are primary awpers, btw) to a team thats also #3 right now.
device is literally the strongest player on astralis right now. why would they kick him? removing your best player for someone who hasnt even been proven to be remotely better is a very poor decision.
the only person that i think is worth removing is gla1ve, but fallen 1. would never join, and 2. doesnt speak the same language. there are still danish igl options that as well. for example, valde is igling for north and is still their strongest player. blameF is igling for heroic and he's carrying them.
the idea of an astralis roster change isnt a bad one, its the arbitrary addition of players of random nationalities to the best danish team.
