Forget Druid -- Templar is where it's at

Templar is going to be amazing, why?

1. Spell Totem -- unless this is gated behind 3 power charges, it will be the best totem in the game :).

2. Consecrated Ground -- currently in the game via the holy descent support and also the consecrated staff. When life regen is so scarce, having a consecrated ground mechanic (like inquisitor from PoE1) should feel amazing.

3. Holy minions -- can I get a shout out for dominating blow? How about holy relic?

I was going to list Armour/ES as a potential "best defense" but technically druid is also positioned as an Armour/ES character. So that's probably a wash between Templar and Druid.
