What are good bases for these Runewords

As the title states, I'm looking for good, not necessarily the best bases but good ones to use in general for these builds.

Summon Druid:

Beast- I currently have an Double Axe

Fire Sorc:

Flickering Flame- I currently have a perfect 15% 30s Demonhead, a Bone Visage and a Corona

Dragon pally:

Hand of Justice
Dragon Shield
Dragon Armor
Flickering Flame

A Berserker Axe is considered best for Beast, because it has good melee stats, but it still has low enough reqs for casters using Spirit. If you don't plan to ever use it on a melee build, then a Double Axe is fine

For Flickering Flame, I would just go with something that you think looks good, with low strength requirements. Bone Visage is maybe considered best in slot, but diadems are popular, and Demonhead is a fine choice

Hand of Justice is definitely best in a Phase Blade for the ias breakpoint. Some people use berserker axes or other bases mostly for looks and run Faith on a merc to hit the ias breakpoint. Or a lot of dragondin players don't care about Zeal and just want to run around with pulse damage, in which case you just go for looks

Dragon Shield is best in a Sacred Targe, but any elite paladin shield with 40+ all res is fine. Exceptional tier shields are...fine, but pay attention to low block rates if you decide to go this route. You could end up wasting a ton of points on dexterity for max block depending on your choice

Dragon armor is mostly made in mage plates for the low requirements, because the runeword gives you +strength. But you could use anything if you don't like the way mage plates look

I know Flickering Flame is popular on a Dragon pally because of the Resist Fire aura. If you don't need the res, and you can afford it, consider Crown of Ages for more damage (with two facets) and a nice boost to survivability
