shield/light templar

so i was playing exile when open beta arrived, and havent played since.

im trying to make a block templar tank, with lightning spells (since im using tempest shield, so it seems a good idea to use other lightning spells too)

what i cant decide is what nodes to pick? i heard at high lvls i need lots of resists n hp... (im 29 lvl) i have 80% resists (which is cap for me) and ~550 hp.

heres my tree http://www.pathofexile.com/passive-skill-tree/AAAAAgUADPcZLhznIPAn7TwtROdUSV8_ah5qO3KpfNmExIrkm-yoGKyqr2y53cT22WHnUunV7w7yL_Pd9kg=


my gear is...well i always try to focus on defense gears. just got a 100hp belt n boots with ~50hp (oh yes how interesting :D )

main skills is: 2hand: cleave, leap strike, molten, heavy strike and glacial strike.

when im in party i use shield n weapon with: tempest, molten, ice nova, occasionally use warlords mark, leap strike, also have shield charge but mostly never use it (just now i saw it that i have it in my build :D )


my question is: what passive nodes i should get now? should i aim for more hp? start my route to static blows? or aim for iron reflexes? any other routes n tips?

also:
1. will i do enough dmg if i go full tank?
2. is it useful in pvp?
3. is it hard to get party at higher lvls?

mainly i want a tank who can laugh at mobs waves...also be effective in pvp

also, should i get life regenerating totem?

anyone?

I'm doing the same kind of build, its really simple. I'm currently using Freezing Pulse as my damage type until I can get my hands on easy access light dmg nodes. currently level 58 and have no real issues farming areas +2 to +4 my level.

Current build:



100 point build:



110 point build:




Auras: Clarity, Purity, Tempest shield, Discipline

Skills: Freezing pulse, Enduring cry, Molten Shell, Enfeeble, Arc on a spell totem.

Get your hands on a iron will gem since this build uses a lot of STR.

so what should i add now? more hp or element dmg? or block?
