I took my Eldar to todays Hivefleet Indy tournament and didn't do too well. I had three good really close games, but I made mistakes, and you aren't allowed to make mistakes when playing Eldar.
I've lost all faith in my Eldar as a tournament army. I have to make some changes, or do something drastic to be able to keep playing them. My GK's are my only army I have any confidence in right now.
