Ya know those big LvB are only good in PvE. Even before the patch no one could live through my 4 x Flameshock, LvB combo without an immunity spell. I havent run into a situation where someone lived through it, so really more damage on it is kinda useless in PvP. I guess you could do split damage on LvB in arena and hope that it would be too much for their healer. Im not that good at arena though =)
