spear is good, s/s is good...they're both good...just wat you prefer (I like heuksal, aggresive style ftw
I think that you've got 2 reasonable options
90 light/weap/ice 30 fire (imo for heavy int hybrid or even full int)
or:
90 weap
90 fire
70 light (you won't really bennefit THAT much if your lighting is level 90 instead of 70
50 ice
This will allow you to run a 34% (if im correct) snow shield. Thus imo this is a real hybrid build, since you havnt got a 60% snow shield...
