Some Advice on where to go with my templar

here is my current Templar build


im running with a scepter and shield with endureing cry & rejuv totem while spamming LS (i also have ambu- that orange armor that shares the endurance charges with the group its awesome , i had been planin on picking up conduit but since i got this armor i might put that off until i know what to focus on)

my LS is linked with Meele physical dmg and Weapon elemental dmg support gems, its currently sitting at 26mp per hit and i can spam it forever

i switch between infernal blow or glacial as single target skills depending on what im doing

im running Tempest Shield and uhm wrath? is it the one that gives lightning dmg

anyway im looking at eldrich battery and how far away it is and i know ive got a shitload of physical dmg nodes to pick up down in the str area, and i also havent picked a main element yet to put points into ever since i started ive been wageing a brain battle between cold & lightning

how would you finish of this build ? im getting torn in 3 ways over it and im haveing a hard time neglecting any of these paths to many goodies in all directions =)

1, Rush EB
2, Focus on Physical Dmg Node's
3, Focus on Elemental Dmg Node's
