Ben, you have to understand two things.
1) Dittos only show who is better at the ditto, not with the character.
2) While I'm no Ferdi, I don't pull out all the stops in friendlies, and even sandbag some in tourneys. Ever wonder why you can't just beat me in a tourney, even though I don't win by much? There's no point in giving it your all and being somewhat spent come semi-finals/finals.
When you say that you're best Yoshi in CO, it doesn't bother me so much, and I tend to bite my tongue. When you say it was SOOOOOO hard /sarcasm, I tend to get pissed.
You tell me to do well with Yoshi in a tournament, yet I have one question for you. When was the last time YOU did well in a tourney with Yoshi? I've come very close to beating Victor's Marth with my Yoshi before, and Kenny's commented on how amazing my Yoshi is. When was the last time anyone really said anything about your Yoshi, hell... Yoshi in general, aside from "Yoshi is stupid/gay"?
Another thing that you should know. The past few tournaments, I've been using a controller that's been verified as being broken by all of the Aurora smashers, sans Kenny. You wonder why my Fox/Peach can play ridiculously fast one moment, then suicide the next? Yeah. I didn't bring it up, because I tend to avoid johning (unless I'm playing Erg or Ferdi, both of them force me to john... seriously... they threatened my family). Fact of the matter is, I do well with a myriad of characters, and with a broken controller, to boot. Don't get pissed at me because you can't travel and play more people/gain more experience so you're not stuck in a perpetual state of mediocrity. The only thing your Yoshi is better at than it used to be is aiming those eggs, CCing, and dtilting from time to time. That's pretty much it.
With all of that said, keep in mind that a lot of **** has been going down this weekend, and I'm in a pretty foul and overly critical mood. I don't hate you, I don't think your Yoshi's ****, and that you have no potential. But I'm not in the mood to really be diplomatic right now. You wanna prove your Yoshi is better than mine? Do something mine couldn't and knock Rafa into loser's bracket or outta the tournament with it.
