yes dark pit, your opinion is valid, but you are wrong in some aspects
1) i dont know how much time you had spend on link, or your brother, but i main link since 2001, in all smash games, so, say than the porblem is " we dont spend enough time in link" is a bad reasoning. I am not an expert or a master in smash, but i kow a couple things about link, and how to use him well.
2) I also win constantly with Link, but in other times i also lose, i play the best i can, but like "beteran" than i am, i can clearly see his weak points and his flaws. If you want to say han link is good, is ok, is your opinion, but, you cant use as argument this "my brother wins constantly" cuz he isnt a pro gamer, either i, so our arguments, if we based in our experiens are just mere opinions.
3) Link is bad, inst a posibility, is a fact, he is slow, have lag on his moves, when he start and finish, his recovery is bad and let us open for a gimp. is true than the second jump conbined with the spin attack can cover a pretty good distance, but al characters can do it as well, and better than link.
using bombs, the boomerang, our good DI, the Zair and the long reach of the sword, we can survive pretty well. but link needs to be fixed if we want play with equals posibilities to win
