I think u should farm a little longer, till 4k+ sp... I didn't farm and I deeply regret that choice cuz I hav a severe sp lackage (and no, I do not hav like 4 trees I'm lvling). For glaive, fire is definitely good, again, only worry about keeping ur weapon skills up to date. For a sub mastery, get only lighting or ice, don't get both. Since u already hav some lightning masteries, keep going with lightning. In lightning, u'll probably only need the grasswalk, concentration buff, and the passive. Force is optional
