Spectre's and support gem's

I found flame sents to be the best allrounders so im currently using (in helm)

spectre
minion damage
greater multiple projectiles (would prefer lesser)
item quantity.

The only times i have issues with them dying is burning floors (mapmod, or golems/magma boss)

If i had a 6Link armor i'd use

spectre
minion damage
minion life
LMP
concentrated effect
faster cast

Life leech would be nice, but its not neccessary. all my flasks are "of animation" so spamming all flasks to empty gives them ~2 minutes worth of flask healing, and they fill my flask charges in ~30 seconds normally. This also then covers zombie health too.

I'm unsure what their max health is, its pretty high but not sure if high enough to make vitality aura worthwhile (probably not compared to determination, disipline or purity).
