I had a question relating to the difference between Physical Level and Class level. From what I heard the physical level is what gives you extra stats and effectively makes you stronger, and class level gives you higher abilities in the class and so on.
However I question what this means in regards to leveling up several classes. If I level say an Archer along with my physical level from the start and get my physical and archer level high, then switch to Lancer it would give me a big difference. Would I end up fighting advanced monsters as per my physical level or low level monsters as per the new lancer level?
I guess in broader terms, how is the interplay between class level and physical level handled in regards to multiple classes?
