Will no duelist comps ever be meta, or even viable, again?
The current map pool is Abyss, Bind, Fracture, Haven, Lotus, Pearl, Split
Historically the only map that has ever seen viable 0-duelist play has been Pearl, and that was during the Chamber meta. The comp in question was KAY/O, Fade, Astra, Viper, and Chamber. Even with a nerfed Chamber this comp could be redesigned to be viable within the current meta, maybe something like KAY/O, Fade, Astra, Harbor, Cypher? This allows at once strong map-control ability, executing ability, and post-plant ability, as well as retaining strong defensive identity. The only thing lacking is an OPer, which is pretty good on Pearl.
Abyss is a strong OPing map, Jett had been in basically all of the compositions up to now, either that or a Yoru-based composition.
Bind has never seen true zero-duelist comps at the high level; Raze (and very rarely Neon/Jett/Yoru) is a staple of every composition.
FPX ran zero-duelist on Fracture before, but that was at the very beginning; Raze or Neon has been present in basically every composition since.
Haven saw Sentinels run a no-duelist comp; again, this was the exception rather than the rule.
Lotus is a newer map and probably saw more experimentation of zero-duelist than I remember, but it seems still that a Duelist is usually meta.
Split is another heavy Raze map, and especially with the prevalence of double Duelist, zero-duelist does not seem very viable either.
This begs the question: why was zero-duelist ever a thing? Well, the Chamber meta allowed for an OPer, and also someone to take aggressive fights on attack. Because Chamber also covered the sentinel role, this freed up a spot for an extra initiator or controller for even more abilities to be used in various ways. Nowadays with the Chamber nerf, any no-duelist comp has to either have a playstyle in which you consistently take and win opening duels, which is a huge ask, or make up for it with the sheer amount of map-controlling abilities, which is perhaps a bigger ask.
So overall, as much as I loved seeing no-duelist comps in 2022, I don't think it'll ever be viable again. You're free to disagree though; I'm just a guy who watches and yaps without much basis in what I say.
Thoughts?
