I have no problem whatsoever with Fieldy. He's taken a new approach to playing, whether it's widely accepted or not. As has been said, Korn wouldn't be Korn without him (it should be noted that I'm not a big Korn, or Fieldy fan).
We can't look at what the kiddies say as gospel. Hell I remember one child several years ago who insisted Hoppus could walk all over Jaco. Seriously... is it even worth debating?
More power to Fiedly for taking a distinctively different approach, making it work, and making a BOATLOAD of cash in th process. Most mainstream pop artists are not virtuosos... And many are rudimentary at best. They are doing what they love and making a LOT of coin. Why hate? I'd love to cut my talent level in half (or more) to be able to live that life. I have no problem admitting that. Do you?
