The Spirit Realm

Hello folks,
I just recently started using my shaman again, and I was wanting to make sure he is at his best as far as spells/abilities go. Sadly, Abilities take time to AA up to and through.Spells however, I can manage at least.

So, my question is this: What spell lines are limited in how long they were upgraded? I have all the 86-95 spells I could get my hands on (need more language to get more), but are there spells in lower levels I should make sure I pick up?

Thanks for any help you can provide.

Thank you. I already have most of those, so only a few to go. Appreciate your time. I didn't find that post when I did my search.
