Okay, so I'm playing through FE6 right now... and so far, I love most of the units. ♥
Updated 8/17/09
Roy; Lord, obviously. Just plain awesome, of course. I'm on chapter 5 right now, and in one turn, like 6 people attack him, and all miss. His strength isn't the best right now, but I'm sure that'll pick up. His speed is more than making up for the lack of strength at the moment.
Marcus; Haven't been using him much, to be honest. I've been busy leveling everyone else up. He's been my village idiot visitor though.
Allan; I kinda love him! He reminds me of a mix between Kieran and Sain (except not girl-crazy). Plus, he's been leveling up like crazy, and he pretty much kills anyone he comes into contact with.
Lance; He's adorable in the 'must follow the rules' way. And he's protective of Allan and Roy, which is pretty cute too. I totally ship Allan/Lance, just like Kent/Sain and Oscar/Kieran and Cain/Abel and...
Wolt; I loved him before I ever started playing the game, and now I love him even more. ♥ And I was one the fence about Wil/Rebecca before, but now I'm convinced Wil is totally his daddy. There's just something very Wil about him. And he's growing just as quickly as Roy, his little support buddy. :)
Bors; Eh. As far as knights go, he's about average so far, nothing spectacular.
Dieck; Let me just get this out of the way right now: Eighteen percent chance should not hit! And definitely not multiple times! Other than that, he's an awesome unit. Not such an interesting character so far, though.
Thany; Well, I haven't used her much because I have bad luck with pegasus units, so she's kinda suffering. She seems like she'd be good though.
Wade; I... I let him go. He died. And took his hammer with him. *tear*
Lott; He's... eh. I'm not so good with fighters. Except Boyd.
Ellen; For a cleric, she's not bad I guess. Her magic is kinda sucking right now, though.
Chad; I think he's adorable in his own special way. And his support with Lugh are cute. Chad/Lugh ftw! I'm noticing a pattern here... Sothe/Tormod and now this?
Lugh; YAY A MAGE! ♥ He's doing awesome so far. He and Wolt were totally taking out bandits by tag-teaming last chapter.
Clarine; I don't like her as a character, reminds me too much of L'Arachel... but I gotta say I'm glad I got a troubadour. Healing + Movement = YAY.
Rutger; Okay, so, first playthrough his chapter, he killed Wolt in a freak accident cause I didn't know he was coming in that turn. Second playthrough, he was stupid an attacked Marcus. And Marcus critical'd him. Third playthrough, I finally recruited him and he was definitely worth the trouble. He's quick and nobody can touch him and I love his killing edge.
Saul; I have this horrible feeling I'm not gonna like him. Probably cause he's so obsessed with pretty girls. It wasn't that annoying when it was Sain, but him? Yeah, I'm already annoyed.
Dorothy; I stole her steel bow and gave it to Wolt. So far, she's a pretty good archer. But I've only had her for part of a chapter then Rutger died. So much for nobody being able to touch him.
ADDED 8/5/09:
Treck; Came in severely under-leveled... and it's a miracle he survived the chapter. He's kinda pathetic right now.
Noah; Actually, he's done pretty well for me, all except for that time he nearly died. Yeah, that wasn't so pretty. And he's only a couple levels behind the other cavaliers [Allan and Lance, obviously since I just said Treck is under-leved] AMENDMENT (8/10/09): I ♥ HIM. MUCHLY.
Zealot; As if I didn't have enough horse-back units... and he's a paladin, which means he won't be doing much if I want the others to get some experience. Although, gotta say, he kinda disappointed me. Allan and Lance managed to take out six units between the two of them. Zealot, Noah, Treck and Marcus could barely take out one between the four of them. The best thing about getting these guys, though? New weapons for the rest of the party!
ADDED 8/6/09:
Lilina; Didn't use her much yet, mostly because she was locked in a little four-tiled room most of the chapter and then I was only brave enough to put her against the boss who couldn't hit her back... and she hit him once out of like ten times, and only did one point of damage, so not too impressed. Yet. She'll get better.
Astohl; Another thief... he seems a little weird. All in all, I like Chad better. And Chad has yet to get hit by a stray javelin, unlike someone.
Barth; Eh, personality is a little dull. Other than that, though he's an okay unit, I guess. I think I like Bors better though.
Wendy; Sadly, she is no longer with us in the land of the living. She didn't quite make the cut. When a knight (even level 1) can't handle two hits with a steel bow... well, I felt no pity for her. It was a quick, relatively painless death.
Oujay; He's pretty far behind Dieck, level-wise, but I think he'll make it up quickly. So far, he's a good unit. Plus, I just love my mercenaries. ♥
ADDED 8/10/09:
Fir; I ♥ her. She grew about three levels in one chapter. And critical'd pretty much everyone I put her up against.
Shin; No kidding - first time I put him in battle, he critical'd the enemy. It was awesome. But other than that, he's average. I prefer Wolt.
ADDED 8/17/09:
Lalum; I'm not much into the dancers and bards... but I like her character. SHe amuses the heck outta me. Especially because Merlinus doesn't seem to like her much. xD
Echidna; Eh, don't plan on using her much because I have two other Mercenaries in the process of being leveled up, so she won't really be necessary. She's cool-looking though. =D
Klein; ...♥ I think I love him. And not just because he's a purple sniper. He's just amazing all around. Worth the trouble it took me getting past his chapter.
Tate; Yeah... don't plan on using her much either. Flying units = not easy for me.
