Uh... I would go with something similar to my build. I have ice and fire imbues, the ice helps out so much in pvp that it is insane. While fighting some other person, fire is great because of the physical attack increase, but I noticed, it really isn't that great. So I use ice to freeze them allowing me to get more hits in and raise the chance of getting that all important critical. ^_^ (Get a blade with high crit. It is more important then anything else on a weapon.)
Also, don't get the ice shield thing that looks like a giant crystal around you. Completely pointless since you need to move a lot. Don't get the mountain shield thing either. It is a lot like the spinning thing that the glaviers use. Completely pointless xD
Other then that just read this:
