Soloing AVs is a different game than EBs. Their regeneration is higher and their damage output is higher. Fire/SD lacks self-healing so it might struggle to stay alive without inspirations. I'm not saying it is impossible, but that it simply isn't worth doing. No mission requires you to do it because you can drop the difficulty so that it spawns as an easier EB when you are soloing.
You don't have access to any PCs? There are builds on these forums, but you may have a hard time evaluating their effectiveness without Mids. I would suggest that you read the forum posts to see how others react to the build to determine if it is a good build or not.
Also, don't worry about getting into a build until you get closer to 50. A lot of inventions are far more expensive in their non-50 form because the level 50 players only find level 50 inventions.
I agree that AVs are in an whole different league than EBs, but a soft-capped Fire/Shield with Aid Self would be just fine for no-temps no-insps AV soloing. I don't have a build to show because mine's a concept build with no heal and all sword attacks. It's kind of the opposite of an AV soloer.

I'm not an expert's expert but, of my farming toons, my fire/shield is the least likely to survive high incoming damage and that makes me agree with the above posters.
I'm not sure your fire/shield would be the ideal AV killer.

Howdy! I've currently got a Fire/Shield Scrapper sitting happy at level 38, and it already can solo EBs. I plan on keeping it red side until I can unlock patron pools, and then I might send him elsewhere.
I lack mids (Mac user), and I was wondering if anyone had a build laying around that can Solo AVs and maybe farm?
Too many alts to list.
