^ that's a very specific combination, but even then against high lvl Grineer, Radiation/Corrosive is by FAR better, since after a certain lvl, they almost mitigate any other elemental damage type. Corpus... well, Magnetic+Heat is a solid option and I'd wager better then Gas if you have Accelerant.

As for Infested.... ugh... that's a hard one... good all-round option I'd figure since Gas only does normal dmg vs Ancients and Corrosive does normal vs. anything except Ancients - meaning that neither are optimal, while Fire is equally efficient vs. all Infested, but not particularly good against any of them (I'm discounting procs here). With the aid of Accelerant I'm tending in favor of pure Heat here.

If you end up with two mod slots to spare, you could also go for a exotic Magnetic+multipleHeat build, since Magnetic does normal dmg. vs. any Infested and Heat+Accelerant would burn though the rest of them.
