i think the problem is the dominant comp on ascent was already jett, kayo, sova, killjoy and omen. Loud and Optic played it at champs as did a ton of other teams. Then Riot's balance changes just made the comp better.
-Chamber got pummeled so the few teams that played him over jett before nerfs now don't becuase how bad he is now.
- Killjoy got buffed so cypher went from a niche pick on ascent to not being played at all
-indirectly sova is now clearly better over fade on ascent since fade can't break killjoy ult and sova can.
The few teams that played the other comps were already playing off meta, now its even more of a challenge to find another comp that could work. I think the killjoy buff and Chamber nerfs were too much, omen needs a tiny nerf or astra and brim need a little of a buff, and kayo could get a nerf or tweak.
