I commend you for releveling a character in FFXIV honestly, it's something I've always "wanted" to do when I was playing but was always really eeeeugh about playing with 90% of my buttons missing while leveling.

I am currently drawing an almost total blank on the actual characterization of the ToB cast (that sounds awful, but I played it a long time ago and haven't thought about it much since) but I do remember really liking Eizen. I liked Magilou but I distinctly remember thinking she'd be a very exhausting person to actually deal with haha.
