no, pure str fire/lightning
if you follow hellsharpt's guide, youll be perfectly fine
h/e im already in the mid 30's and sticking ONLY with lightning and fire is a bit boring, so i just put in some in ice imbue/buffs as well with lightning
since fire is my main imbue, i dont need high lvl imbues of other skills, but i do have the other imbues at around lvl 5-8. this is b/c if i escort lvl 20s on trade runs, do i really need to imbue book 2 fire along with my book 2 anti devil on a blue thief? not really, a low level ice with anti is more than enough. This is also handy for earth ghosts and w/e mobs are on dw side as well.
i also got nova wind, and some force skills, just because i got bored and wanna do something else, llike ressing and harmony(very practical and useful) and freezing people in pvp for fun.
sure it uses quite a few more sp points, but wth, im not reaching lvl 70 anytime soon. just my thoughts for you to consider
