I would say that take sword and shield instead of spear. I just changed from spear to sword and i am more than happy now. I make almoust same dmg and i have much more chances in pvp and pve, becouse of shield and kd/stab.
If you decide to go sword. Max out Knock down and stab attacks, and passive. Other skills are optional, but kd and stab are skills you will need for sure!
You can choose between hybrid and pure int. If you go hybrid i would say to go 1:2 or 1:3 but keep your mag balance 80% or more so you make enough dmg with nukes.
Masteries could be something like this
Sword/(or spear) 80
Fire 120
Lighting 100
That is just my opinion you can also have 120 ligthting and 100 fire, but depends what you like.
I hope this helped
