I'm a huge collector, and I really hate to miss out on something and being forced to remake. Is there any sort of database or guide that shows what you can miss out on? I know there's a bunch of extra bosses and such just on the starting island alone, which I assume you can't get back to after leaving. I would hate to miss out on any armor pieces and such.
You can go back to the starter isles since they were added back. As for a list, I guess you could look in eq2 wikia/ zam for mob drops and on eq2u.
