Who do you think is a better swordsman Link or Ike? Personally I think Link who cares if Ike has two handed sword Link can do all those super cool moves.
Have any of you guys played the Fire Emblem game Ike is in? If not, there is no way in hell you can judge him from SSBB.
True enough, Ike was a much better fighter in his own game, he wasn't slow, was a great tactician, and could take on the Black Knight (If you leveled him up right) Then you give him Ragnell and he gets a ranged attack too.
Not to mention they made a sequel of that Fire Emblem just cuz he's that good.
I don't know, Link has beaten a good variety of bosses, he's pretty resourceful.
