Ascent and Haven is the 2 maps that had been in the map pool for the longest, It's getting pretty boring to both play and watch them in my opinion.
Ascent 100% should be rotated.
It's the most stale map compositionally wise in the map pool.
The kj-omen-kayo-sova-jett comp has been the "optimal" comp for over a year now.
Ascent comp pick frequency at champs:
kj-omen-kayo-sova-jett: 13 times
fade-jett-viper-omen-breach: 1 time
reyna-skye-harbor-raze-viper: 1 time
skye-kj-jett-astra-omen: 1 time
(There has not been a single game at champs when neither of the teams playing played the "optimal" ascent comp)
