If you play Falcon you'll get better as a player alot quicker then you would from using most other chars, because you'll lose more, and you always learn more from people better than you than one's that are worse. You'll also have to learn how to properly space, bait, and punish etc. because your character is so bad.
But you shouldn't get discouraged from him because he's bad though, make your goal to be a good CF, not just someone who places well in tourneys, you can still be a respected player even if you don't place well because people will acknowledge you're good, just using a bad character.
For example Reflex, who is the number one Pokemon Trainer, only got around 50th at massive national tourney, yet everyone still knows he's a freak at this game.
Plus, there is nothing better in this game than landing the Sacred Combo (good luck landing that though).
