yeah the 6% nodes are pretty by themselves. especially to 1 element.
you have to remember all +damage are added.
Lets say you have a 200 damage skill. Pulse. +20% elemental, +10% spell power, +20% cold. Those all add for +50%. giving you a 300 damage pulse.
+176% in that

Probably another +70% on weapon? And pulse/cold pen can have more +damage as well.
A single 6% difference is pretty tiny.
200*3.46= 692 or 680
Crit is directly related to how much crit multiplier you have of course.
Spell damage and crit scale of each other as well, obviously as well. If you have +300 spell damage, and only 10% crit. crit is going to be very useful. while if you have +200% crit, and 300% crit multi, and only +50% spell, then spell damage will be ideal.
This is my crit/cold witchs current.

No +damage passives yet. Relying on weapon/skill/gear so far for that.
My pulse is like 25% crit chance for +450 crit multiplier.
2 fitness give 54 str, for spell totem, purity. as well as life.
95% es recovery.
Deep thoughts wasn't part of my original plan, but I couldn't afford 3 auras, so grabbed it for more mana. Its still tight, more int nodes and better gear will allow, purity, disc, and clarity all the time.
I'm at like 55mana/s regen at level 46.
30ish evade, 900ish ES. dont remember exacts, changes as I swap gear of course.
next priority is shocking blows and divine toughness.
End gamish. alot of the obvious extras are up for grabs.

Current skills.
Pulse/lmp/faster proj.
Spear/crit damage/cold pen(12%)
arc/spelltotem/faster cast (faster cast is really needed on spell totems now)
disc/clarity (cant afford purity realistically atm)
firestorm.
elem weakness.
Upgrades will be elem proliferation for arc totem. temporal chains+elem weakness.
added lit or faster cast for pulse. mana for all 3 auras.
High precedence on defense on gear. 75% elem resists, 25% chaos in cruel. life and life regen
Spear is good on totems, with LMP. I've considered it. the totem nerf, hurt arc totem pretty bad.
