NA Group Stage Meta Week 1-3

It's going to be interesting to see how the meta changes with the new patch but as of right now we are already in a double controller and double initiator meta.

Here are the top team composition picks from each map (>50% pick rate) from the NA group stage week 1-3, in descending order.
Bind: Astra Sova Viper Raze (Jett, Chamber, Sky) = team preference
Fracture: Chamber Breach Viper Astra Raze = double controller
Haven: Astra Jett Sova Sky KJ = double initiator
Breeze: Sova Viper Jett KayO Chamber = double initiator
Ascent: Astra Sova Jett Killjoy KayO = double initiator
Icebox: Sova Viper Jett Chamber Sage = double sentinel
Split: Astra Raze Sky Viper (Chamber/Cypher) = double controller

It is interesting to see how the meta will have evolved from week 1 to week 5. When the new patch gets implemented for pro play, things may change even more.
As of right now Raze and Jett are the only Viable Duelists (4 out of the bottom 5 agent picks are the other duelists), but soon Yoru may be viable and Astra certainly will be affected.

What are yall's thoughts?

Icebox teams tend to run Kayo in place of either Jett or sage

The number of teams that ran Brim on fracture slowly started to dwindle, so I'm excited to see him potentially come back on Fracture and other maps!

omen on split and brim on bind but otherwise this seems valid

Brim viper on Bind might reappear and I think Omen might be decent on split, I always thought it was one of his better maps, and I guess Viper Omen could work decently.
