Ooh, awesome. Here's what I disagree with. I'm probably wrong though since I haven't looked up growths and stuff, so it's all personal experience, which, of course, means nothing.
Top
Leaf - I'm not seeing this...sure, like Marcus, he's destroying everything earlygame, but, also like Marcus, he gets worse and worse as the game goes on. Paladins in this hack in general suck for me actually - I've used Leaf, Glenn and Plum and found them all mediocre.
Sanger - Should be right at the top, pretty much no flaws. Joins one chapter after Leaf and beats him at everything.
Glenn - What? Einlanzer is the only reason I can possibly see for this, but it's not actually locked to him...his stats sucked both times I tried him out...
Ninian
Mia - This is just silly. She's made redundant because Nanna can move further to heal, and Linoan can attack as well as heal. There's pretty much no reason to use Mia, ever.
Altenna - Maybe move up a little.
High
Linoan - Should go just below Sanger in Top. Three weapon types from before promotion, by far the best healer (Mia should not be above her, just no) and no real flaws at all.
Raymond - This looks about right, but I'm thinking maybe he should be at the bottom of Top. He starts off mediocre but becomes amazing.
Nanna - She's the best choice for secondary healer (Linoan being primary), so maybe go somewhere in Top.
Milanor
Sakura - Her incredible offense doesn't make up for her terrible defensive stats. It can be cured with an Angelic Robe and a Dracoshield, but items should have no part in tier lists.
Kid - Is this just for thief utility? Because she's useless at fighting and Matthew does the job just as well as she does for thievery.
Raphael - Probably needs to go to Top because of crit bonus, and being the only good axe user.
Kyosuke - Needs to go down, he can't keep up with everyone else and has trouble one-rounding.
Chris - Needs to go down, he's amazing but comes too late to be this high.
Jessica - I got Anne, so no idea.
Middle
Heather
Katherine
Excellen - Should go down. Joins too late and is useless on enemy phase.
Issac
Ellen
Karsh - Should go down, his speed wrecks an otherwise good unit.
Jenny
Anne
Eliwood - Should go up. Like Raymond, he starts poor and gets better and better. Certainly better than the likes of Karsh and Anne at any rate.
Marcia
Low
Cruz
Viper - There shouldn't be such a gap between Kyosuke and Viper, they perform very similarly.
Alex - Should go to Bottom just because he's only there for 2 chapters.
Kent
Sain - Should move above Kent, he's better at just about everything.
Plum - Should go down to Bottom, she has basically no use.
Edmond - Move to High or possibly Top. Luna is broken, his HP is ridiculous and he one-rounds anything easily.
Matthew - Nobody who has good availability and thief utility should be this low.
Steena
Kyle
Tempest - Should go to Bottom. Locked to the worst weapons until promotion, and he won't promote until close to the end with his horrid availability.
Bottom
Mel
Luna
