Percival- He's consistently good, regardless of stat gains, and typically excels over the other potential Paladins. He has a wonderful color palette with the dark/ navy blue, and has a respectable personality.
Clarine- early join time, and has consistent superiority in terms of skill, luck, and speed, making her excel in arena grinding at the very least. She gets enough magic to pass in combat, or destroy everything that dares look in her direction. Her high movement also makes her a very efficient healer and rescuer. I lover her prissy, rich noble demeanor, which definitely accents her perfectly.
Lilina- She easily caps magic every time I use her. Her speed can be shaky at times, but typically doesn't ever fall too far behind. Only flaw is her dreadful skill, making her accuracy on bosses a bit low, but nothing some supports can't fix. She is a total sweet heart, seen in some of her recruitment conversations, and I just love her personality.
Ellen- (putting her separate from healers in general, since she uses light magic) I like Ellen over Jodel and Saul due to her high magic, skill, and luck. While Jodel does have many similar stats to her, he starts at max level, so Ellen has much more room to improve. She can wind up fairly slow, but is fast enough to last her through the game and her high magic makes her light spells very potent. She isn't too important in the story line, but she's quiet and laid back, which I can relate to.
Douglas- In all honestly, I don't really use knights or generals period, due to the low movement and accuracy and speed. Douglas does support with better units such as Cecilia and Percival, and starts with excellent weapon ranks and base stats, so he easily tops all other armor knights. He is very honor driven, and very dedicated to what he believes in, something I admire (and is also good at running in circles).
Zeiss- Personally, I have had a lot of success with Zeiss in contrast to Milady. He gets higher strength and defense, and typically stays in equivalence with her in terms of skill and speed. His HP is good, and has typical resistance and luck for his class. His supports don't help him much, but he definitely has his uses. He is very stern and supportive of his country, but is also very honor bound for what is right.
Niime- She comes in fairly early for her level and comes in with a great inventory, weapon ranks, and very nice bases, only lacking in HP. This is easily fixed with Angelic Robes which can be bought in the secret shop of Chapter 16, easily buffing her to last a lot longer. She has quite possibly the greatest capability in terms of long range staffs, with Apocalypse to further bolster her range. I love her personality as a crazy old lady dedicating her life to magic, and her design and color palette are flawless.
Sue- Joins sooner than Sin, and has more room to grow. Her bases for her level are overall greater than Sin's. She is typically faster and luckier, thus making her at least good at dodging.
Klein- Has very shaky bases for his level, and poor growth rates to match, but his supports with Elphin and Clarine can help fix some of his setbacks, and his growths do allow for some usage, and in some cases may result in getting upwards of 20 in strength, skill, and speed. He has a very nice color palette, and a respectful personality about him. Also, Wolt hates me and refuses to get any stat other than HP, maybe skill, strength, skill, and speed are out of the question.
Chad- He has very high skill, strength, speed, luck, and HP, making him efficient for dodging and combat. The only downside is his lack of promotion. He is also very frail, so if he does get hit, the enemy will rip through his HP, but he will survive.
Roy- I typically get very bad luck with Roy, barely pushing 10 strength and 13 speed on average by level 20 in his base class. His skill, HP, and luck are usually fine, but his defenses are pretty low consistently. He usually improves upon his shortcomings upon his very late promotion, but still lags behind in terms of other sword users.
Elphin- He typically gets more HP and defenses than Lalum, and still gets a hefty amount of speed and luck to boot. He oddly gets a decent amount of skill, though useless.
Fae- She is utterly broken, only being held back by her weapon's durability, limiting her usage. She gains a level with nearly every kill and has astounding growths. She has low HP to start, but grows quickly and does heavy damage to all enemies throughout the game. She does bonus damage in the final chapters, where she is required to be brought, and in some cases, can knock out enemies in one blow.
