Mmm, not much if I remember right about those stats. I think those are pretty much ingrained in a character. Though, cheer may be permanent, but I really can't remember. I never really payed those stats much attention myself tbh.
And yeah Lancer was one of my favorites as well, actually it was my favorite. If you do a legit playthrough, meaning you don't dupe any of the most powerful swords or weapons in the game, I think Lancer has the best damage output, as well as a very high survivability. Also, one of the best weapons is a lance that you can find on a map, the ability move/find item is needed. It's kind of a sidequesty type map though so not a lot of people get it. I never play the game without a Lancer though. Monk I always liked as more of a subjob rather than my primary class.
Though, my party setup was pretty standard imo. I was never very caster friendly either, though I did use a time mage/priest once lol. Usually I end up with a squire(Ramza), a lancer, and a bunch of knights lol.
