These threads are good... they're always filled with idiots that obviously have no idea what they're talking about. If you're going to try and say something supporting your opinion, before you press 'submit' or 'post quick reply', take a couple seconds and FUCKING READ your thoughts that you just typed.
If anyone says what Zidane says is wrong, you're only making yourself look more like an idiot. He understands the game on a level that you wish you did. Stop making yourself look like a scrub by not using common sense when it comes to BB and fighting games in general.
Also, I wouldn't compare Jin to Lambda but I will tell you why she is in her respected tier:
Bang walks over her: nails destroy her neutral game, she has no solid reversal to get out of his mixup/pressure/oki game, and since she can't keep him away (he rapes her up close) it only makes matters worse.
Litchi walks all over her: same reasons as above but probably worse... staff/fastfall ruins her neutral game and you only need to get hit 2-3 times.
Hazama walks all over her: chains destroy her neutral game and his normals rape her. He's a combination of Bang and Litchi.
Ragna is tough but do-able: keeping him out can be a guessing games at times, but if you condition him to take chances you can win. Once he's in his normals walk all over her... 2-3 combos and you're dead.
Hakumen is doable: DON'T GET HIT. He can just turtle and make the next hit hurt... a lot.
Tao is just better all around except for not having a reversal, but Lambda just has a hard time getting in the hits (in Tao vs. Lambda that is).
Arakune: not a bad matchup for Lambda but his damage output is far beyond Lambda's, keeping him higher up the list.
Jin: his average damage isn't that great but he makes up for it by being good all-around. He's about as average as they come.
And this is where Lambda is, but for different reasons. She gets wrecked by characters that have an easy time getting in (or can just turtle), and her damage relies on where you are in the stage. Her good damage starters are generally risky and her mixup is mediocre. Her strength is trying to force opponents to make bad decisions and then capitalizing. She's 1/2 way between an awesome character and a shitty one. She's better than everyone below her, even with Jin, but worse than everyone above her, even if by just a smidge.
If that doesn't help explain why I don't know what will.
