It's not really that amazing. I had an ele build once that I was able to send two warrior runnin for their lives. It was an air build, basically you wait till they're almost on you, then blind them and hammer away at them. Make it an E/R and lay a trap or two and just don't move so they have to come to you. Between being blinded, degen from the traps, and some air spike, you can send most any tank packin.
owning warriors with ele isn;t that hard :P be earth, take magnetic aura or whatever it is called an spam to death with obs spike.
or take the 200 armor build thingy.. that works too :P
Water magic is designed to pwn warriors. In 1 on 1, cast ice prison, rust and blurred vision on them. Just stay out of their reach wich is easy because of Ice Prison. Spam Ice Spear and if he gets to close use Mist Form (elite) and he wont be able to hurt you. If he uses a healing sig, he is dead because of rust and the -40 armor. Give it a try, I've never lost to a warrior in a 1 on 1 this way. ;-)
