Recouping experience on weapons is a fool's errand since the weapon your leveling hits breakpoints where you have to stop and do something else, and the excess is wasted. (I assume. Maybe not. Enhancement ores actually refund you the difference when you go over now.) Either way, I still wouldn't level a weapon you don't intend to keep around.

Agree with Swifty in that you should stick to one team up through the point where you get to AR45 and can start farming 5-star artifacts. Once you feel comfortable at that stage with your main team, you can start branching out.

I'm a big believer in that you should play at your own pace and explore and quest only when it interests you. Unfortunately, Mihoyo doesn't seem to agree since they lock so much stuff behind main quest progression.
