Guys please help me out,

I just recently decided to go test out my skills or whatever have you with some 1vs1 outside org.
I got demolished by a warrior not even funny, i got completely destroyed by a priest and then!
A level 85 lock i think it was killed me, which i think is quite bad but not sure.

He completely controlled the fight fear-fear-fear. I thought i knew what i was doing with this
windwalker while doing bg's but that recent event left me a little scarred lol.

I would like to know if windwalkers are actually that bad or you can say i suck if you want :'(

Also side note i know the gemming is bad for pvp i just used what i had at the moment.

here's my armory:
