Sudden lag spikes, but input delay, by far.
Last Stock SDs. The player pretty much pulls a Cartman and gives up. (If there's awful lag, then I wouldn't blame them.)
Pretty much every Link / Toon Link, Ness, Samus, etc. spammer. Gettin' real sick of your bait n' switch junk, ya old farts. Power Shield / Reflect / Counter / Super Armor 101... (Never a Jolt Haymaker, cause... *coughs*) It's just a practice session now.
The lack of Decent Macs. Even before the patches, I don't think anyone has played him efficiently...with the exception of a few I've seen on Youtube. Many of em are already kicked offstage or-......Ohh. *sees a shooting star*
As a Falcon main, I can agree with the earlier posts that he's getting too...overused and repetitive. Most of 'em play like scrubs with usual Dash, D-Throw and Up Air. I love Falcon montages as much as the next guy, but these dudes need a lot more moves to show than this, I mean really... Perhaps playing some F-Zero X will be a fresh can of Pepsi as I get my mind off the thought.
