...oooooooooone moment.
Just to clarify to make it easier for me to understand...
In FFT, you keep changing classes to get certain abilities, which when mastered, can be used on any of that unit's classes (but 1 skill in a particular category at a time).
Is this basically the same concept in Fire Emblem? To repeatedly change classes (not immediately, but when skills are learned) to learn the skills and then finalize on 1 class?
