L75 Bird Build

I am endgame pvper and have been losing a lot could someone tell me a good build?

Hmmm, you can try

9 Buffs
9 Blast
9 Break
9 Thorn Root
5 Avian Scream, to Un-Stun yourself
8 blind
1 Shattering Scream
9 Repulse
And the rest you can put either 3 in Thorn wall and whatever in heal, or you could put it all in thorn wall or whatever you feel like :)

This isn't personally what I use because I changed it to how I play, you can change this build to however you want to play after experience. :-)

Good Luck!
