Tank and Healer class suggestion.

I can understand their alchemical developments, but according to the lore, they are not very advanced in technology, so firearms for them seems like a stretch.

It depends on what kind of weapon tech it is. Maybe not something like what we see with MCH, but something like a small launcher isn't exactly that much of a stretch for an alchemical delivery system, whether it be a small, simple shoulder cannon or a simpler launching device like a bigger crossbow or a smaller catapult.
