People misunderstand Gas. It's not about the damage (you have enough damage anyways). It's the proc. Thus, you don't use it against Infested: due to most big enemies being Fossilized and the existence of Toxic Ancients, it's terrible there. What it does do is allow high proc high base damage crit weapons (Lanka, Vectis, Vectis Prime, Dread, Rakta Cernos, Paris Prime, etc.) to deal AOE Toxin damage.

This is of course insane vs. Corpus (ignores Shields, +50% to Flesh) but it's also strong vs. Grineer/Void if you remove armor with Corrosive Projections. AOE damage is very hard to come by and the damage is quite good. While the elemental mods themselves don't add to the Gas proc, Serra/Heavy Caliber/Point Strike/Vital Strike do and status mods/multishot/rate of fire produce more procs. Thus as long as your weapon has a good status chance and you can make do without raw elemental mods, you'll have all your mods contributing towards your AOE producing incredibly powerful effects. Remember that headshot multipliers apply to the proc too thus turning your single target massive overkill into 10m diameter AOE overkill.

Gas can also be used to good effect on lingering AOE weapons like Synoid Simulor or Torid relying on the sheer quantity of procs to reach reasonable damage levels. In a world where you remove armor from enemies, it's incredibly powerful and certainly a competitor for Viral on high proc crit weapons. It becomes useful much earlier (indeed, it's always nice to be able to take out enemy hordes with but a single proc) and remains useful ad infinitum. In Warframe, a game focused around enemy masses, AOE is never superfluous.
