I relate to how you feel.
As much as I've loved attending Kumoricon the past several years, there are times where I've felt frustrated over lack of new guests, too.
I like the fact that they started getting more names a few years ago and I appreciate the guest departments decision to do that.
But I was at the same time, hoping they'd start getting new faces. Even though I really liked the guests they got in '13 and last year, they were mostly names that had recently attended a Washington con. And that was why I chose to do Sac Anime last year, even though I would've loved to have met Karen Strassman.
It was an easy and difficult decision at the same time. Easy, because Sac Anime had more guests I wanted to meet.
And difficult, because I had been attending every year since '05 and I would've enjoyed meeting Stephanie Sheh, Bryce Papenbrook, Christopher Sabat, Chuck Huber and Patrick Seitz again.
But although I didn't want to skip Kumoricon and wished Sac Anime was on a different weekend, it turned out to be a choice I was happy with, because I got to meet Yuri Lowenthal, Tara Platt, Josh Grelle and Sam Riegel for the first time.
I haven't quit attending anime conventions in this state and I don't intend to, but temporarily I'm being selective of which cons I go to, so I can meet more new faces.
I also got to meet Cherami Leigh, Dante Basco and Charles Martinet last year for the first time and am currently aiming for Eric Vale, Jerry Jewell and Greg Ayres.
If any of those three names can make Sakura Con or Kumoricon next year, then I'll do whatever I can to attend.
