Hellos!

Returning player here... and a little....

BACKSTORY:
First account i had WHM68/others40's, quit for a while... lost the characters and account info BLAAAAAAAAH.

Current Account:
Name: Heavens
Jobs: RDM 62, BLM 40, Pup 30-40ish? (LOVE PUP)
Server: Asura
Linkshell: Sadly None (looking for a home)

Never did endgame stuff, had a few friends that played and got the AF, did some CoP, minor parts of Zilart, and only did some Campaigns for Wotg (yeah i missed out on a lot! BOOO!)

So i did some research and saw that it was pretty much a MUST to get the Abyssea stuffs if i want to go anywhere. So here are my questions:

1. Do i need the other add-on packs for this?
Note: I never really did maze mongers, or any of that stuff... missed out on a lot.
2. Would i need to purchase all three abyssea packs?
3. What level range does it start (for xp, xp parties, etc)
4. Can i solo on the pup with Abyssea content?'
5. Add anything else you'd like to know.. please add!

Thanks all!!
