I'm enjoying Abyssea. To me its like a faster paced sky with far more variety. In sky you killed maybe 12 or so NM's all the time. In Abyssea its like a 100 different NM's that get killed for various drops, KI's, seals, +2 items, Emp items. Dynamis and Sky used to be my endgame life and were certainly more tedious than Aby is.
And I don't need my endgame to be nail-biting "am I going to survive" tough to be enjoyable. If it challenges my thought processes and makes me use most of my abilities I'm happy (and certainly soloing a lot of NM's on DNC and BLU does that).
My only complaint is how my favorite jobs COR, RNG and RDM have become less useful. Have played RNG once in 8 months. COR maybe comes out once every couple weeks. RDM gets a bit more use.
