swg credits, Star Wars Galaxies credits, swg Gold, I find this personally best for solo play and farming, but it is also good for

Light Fire /Arcane: This is a trimmed down version of the fire build above with more swg credits attention paid to the aspects of raiding.

The fire tree is gutted of all the none powerful talents so you can put more points in arcane for greater mana efficiency. Your arcane spells will also be more potent, but you will only really be using arcane explosion for AOE.

If your gear has enough spell hit you can take one point out of Elemental Precision and put one more in Arcane Meditation.

Fire Frost Elementist: This is a hybrid build where you will be relying on your fire spells for damage, and your frost spells for control and support. I find this personally best for solo play and farming, but it is also good for five-man content and ten man raids.

PVE Frost: This is in the same vein as the fire arcane build but uses frost instead of fire. You will be relying nearly one hundred percent on your frost spells for damage. Frost is very strong as a PVP tree, but suffers a little in the PVE department unless you are playing solo.

Most mobs in instances and raids will be immune to freeze or chill effects, which are the key to frost DPS. It's still an effective DPS build though and makes an excellent grinding build.
