Lyndis
Popularity: She has some popularity, but not a whole lot. She's less popular than Marth, Ike, Roy and Chrom, and probably less than Lucina as well.
Relevancy: She was the star of an FE game, the first one to be released in the US.
Design: Yet another sword-using FE lord. No more interesting than the others.
Roster: More female, looks less similar to the others than Chrom and Lucina do at least. I think an FE newcomer (or Roy, who I guess technically isn't a newcomer) is pretty likely. It's not a lock though. Four reps seems pretty unlikely to me. Just because FE fans are rabid and seem to want this game to be "Fire Emblem Fighters: Guest Starring Mario" doesn't mean Sakurai is going to attach more importance to the series than it deserves based on sales. FE fans are passionate but they're still a relatively small group compared to other series. Also, FE characters are fairly similar to each other and to some other potential newcomers representing NEW series (all of whom I'd rather see), which makes four reps even less likely.
Competition: She's got some serious competition from Roy and Chrom, and to a lesser extent Lucina.
Lyn chances: 3.3%
They're competing for most likely only one spot, and I'm pretty sure Roy (super popular among Smash fans) or Chrom (popular among FE fans, star of most recent game) is going to be it. She's only become less relevant since Brawl, so I give her slightly worse chances than Lucina.
Lyn want: 38%
(50% = indifference) This puts her among my most wanted FE characters. Basically because she's from the only FE game I've played, she's female and she doesn't have blue hair. But like other FE characters... meh. I certainly don't want them taking up more than one newcomer slot, and with so many options, I can't muster up much desire for any specific FE character.
Chrom prediction: 75%
Chrom fans seem very, very confident. Of course, not everyone is so confident, and some will rate him lower because of Roy and Lucina.
Nominations:
Ugh, well, I give up on delaying FE reps. I helped push Jigglypuff, Ice Climbers and Lucario above some of them, but looks like Ike and Tharja are coming soon no matter what, so whatever. After that we'll be done with the glut of them... But we'll still have to rate more of them later. Because FE fans for some reason feel the need to hear "yet another sword-wielding FE character with no chance, I rate 0%" over and over. Might as well nominate Prince Peasley, Tiny Kong, Jody Summers, Goomba and Skulltula.
