Triple Sentinel (no duelist) Icebox Comp

The triple sentinel icebox comp (Chamber, Sage, KJ, Sova, Viper) seems very strong. Teams walk up to a site, get a plant and then play post-plant with Sova, Viper, and KJ (defence is strong anyway with 3 sentinels and viper). I think this comp was started by G2 if I remember correctly.

How do you think other teams can counter this in the upcoming matches?

To me it seems as dominant as how the acend bind comp was for a time. I think to counter it you would need to play heavy extremity control with garage and mid. I'm not a pro player though so my opinion is useless.

The only way to counter this comp is not letting them get site. IMO the comp that m3c and optic use with brim and his molly is very good for denying site however it is weak on the attack especially attacking b site without a sage
