It doesn't matter if they can't be chaingrabbed by 1/2 the cast or not. Someone will play Marth or Pokemon Trainer against you, and chaingrab you to death. Even if this wasn't known about, Ness and Lucas have enough bad matches to warrant having secondaries (which is what i'd suggest to everyone anyway).
Whoah, bad matchups? Who said they have bad matchups?
Seriously, this thread needs to die. All it's doing now is pulling people away from Ness and Lucas. For the last frikkin time, only Marth and PT can infinite Ness and only Marth for Lucas. Also, Ulevo said that you can dodge or jab out of dash grabs and other attacks.
Like Tyr said, we can take it from here. We will just warn people about not playing against a Marth or PT, instead of having a thread flaming these boys and making people quit.
Besides, Ness and Lucas are made of win. It's your opinion if you think they deserve middle tier, not a fact.
