Yes. Try to keep the monsters around decent challenge to ep+. You'll have a easier time keeping skills in check. Just because a page caps out 15-20 levels after that doesn't mean you should stay there. 75 for Aby I would say yes, but because levels go by extremely fast, your skills might get left by the wayside. This was my problem when abyssea was introduced, and I have yet to cap ranged and melee still.

My advice would be to maybe gain like 5 levels in Aby, get out and cap your skills with GoV, go back and get another 5, etc.
