i dont have a elemtalist, just tested him and we have a few in the guild with which im talkin often. i tested him with 30/30/0/0/10 or something (completly dmg. in pvp)
also just played on lightning and rarely switched to fire, gear wars berserk style. cuz of dmg.
it is easy in low lvls. u just need the combo field fire and thats all. play with scepter dagger and there are all your blasts which u need to get tons of might.
(in normal PvE solo play its not needed but in dungeons against a boss its really nice.)
