Thank you. Is this in order? Or are there some more important than others?

Hi everyone,
I have two questions.

1: Can my already spent AA’s be refunded allowing me for start over?

2: Where can I find a list, start to finish on an AA progression?

Thanks in advance

Hi all, I'm also a returning player who has found a plethora of advice and information on here. Thanks for all of your input. I'd be lost without it. My question is about grouping. What are the LFG times like for an old mage well below max level? Also, is there a certain number of AA's I should have...
