I've met Vic Mignogna a couple of times. The first time I met him I was SUPER freakin' excited... I loved him, he could do no wrong. It was in 2006 when the first FMA was out and I was at the height of my obsession, I was dressed as Edward Elric and handed him a painting I did for him and everything. I met him again in 2010 and was not so impressed, he's either changed or I was blinded by the stars in my eyes the first time, but he'd turned into a complete jerk! He's slated to be at SakuraCon in a couple of weeks and I hope to freakin' hell he was just having a bad weekend or something because he seemed like a real sweetheart in 2006, I was totally disappointed in 2010.
I've also met Chris Patton, Todd Haberkorn, Troy Baker, Wendy Powell and Luci Christian - Sadly by the time I had met all of them I had completely forgotten about their roles in FMA and gushed at them over various other anime roles I was a fan of, but they were all still cool.
The one FMA VA I am dying to meet though is Travis Willigham - Roy Mustang! As well as Colleen Clickenbeard and Sonny Straight (Riza Hawkeye and Maes Hughes), that would be so awesome. If I managed to meet those three then I will have met all of my favourite characters' voice actors O.O
