BEASTCORE

Looking to try my hand in pvp! i currently have a fire/fire/fire blaster, which I mostly use for fire farming. but obviously it's an entirely different animal with pvp, and the build. ive seen a fire fire blaster take down 1 of those training dummys in under a minute.. and was mesmerized. he said he was mostly pvp. so.. now i want to make an absolute savage of a blaster.. any help with the build and enhancing would be appreciated!
