I understand that, all of my characters are pretty bad online. Your Falco wasn't as good, probably your worst. He's a good character if you take the time to learn him, but his recovery's just as gimpable as Link's. On wi-fi, anyway. You also can't consistently SHDL, so that was a major setback. Your Ike was a little Fsmashey, but good nonetheless. Your jab cancelling could use some work, because you just constantly rolled behind me.
The only problems I saw with your general playstyle; you roll. Too much. If you got the first kill, I could always hold a DK Dsmash, and wait until you rolled away from the ledge. Near all of my kills were from doing this.
And the only other problem I saw; you're too agressive. It's not a bad thing, but your Marth especially suffered from this. The best thing he has at close range is Dancing Blade, which I saw very little of. It's an amazing move, use it more if you're trying to get inside.
