Having hit level 52 and 191k reputation, I suppose I've reached the mid-ish game and am becoming increasingly confused by the buddy system - specifically by which buddies I should have in my party and be working on leveling and improving, and when I should replace them. At present, my team consists of Norns, Ajani, and Lisa, with Ronny leveling up ever so slowly because I keep getting battleaxes and she had a giant red "Advised" on her picture in the tavern. I haven't spent anything on this game as of yet, so I don't have Flora or Little Athena, or any heavy hitting angels.
I'm aware of the basic gist from here (viewtopic.php?f=23&t=7447&p=14567&hilit=buddy&sid=add2a87b03ae133dc66c401f764b393b#p14567) sort of leading into the endgame, but am still having difficulty figuring out how I get from where I'm at to there.
I know Lea's the first big "Must have" in every guide, but where does she fit in to my team? Who does she replace?
Zephyrtail and Diana are both listed as "Advised" in the tavern. Should I grab either of them? If so, where do they fit in?
At what point, and with whom, do I replace Norns?
When do I start to put more than basic level potions and leveled gear on buddies?
Apart from the list in that link (Lea, Tia, Aileen, Lacus, etc), are there any others I should keep an eye out for?
Sorry for the question dump, but I've been trouble finding specific answers to those specific questions. If anyone can provide any answers, or point me to somewhere that has them, I'd be truly grateful.
