because they are simply better than COL, Spirit and C9. their playstyle and mappool is very impressive but glaive is back to igl so I dont think that they will lose. they can win on train but idk
and I will not be dissappointed if my boahs lose, but it seems that it will not happen.
its about strats. astralis can neutralise high frag teams easily. i dont know avout gambit strats. maybe they will sacrifice some players to make their name true
