The easiest to build of all druid options, as they have no issues with setting r6-r7 aside for druid. Don't be fooled by Lycanthrophy however, it also scales of int.
There have been quite a few changes to the magic classes though, and not all for the best:
Bokor is still quite good, but benefits far too much from plague doctor2. Druid doesn't really fit into that build at the moment.
Priest's exorcise now lasts for 1-6 hits before expiring. Making both exorcise and magnus potent damage skills.
However chaplain+druid is quite taxing build wise.
Chaplain/Druid3 will have sub par healing, and likely needs to avoid spr and thus has a rubbish stone skin.
But if r9 options aren't as amazing then miko will be a better option then chaplain.
Krivis got stronger than ever due to Taoist's storm. Which also synergizes well with hengestone for a guaranteed good r9 option.
Miko is amazing damage for an int build, but sadly competes for a rank of druid and sterea trofh + clap does not work atm. Miko>druid2 is a decent combo but lacks damage and heavily depends on a holy dmg necklace or decent r9/10 classes to function properly, as such I won't recommend it just yet.
In terms of the rank 8 options it's not that amazing however.
Inquisitor needs testing for its scaling and interactions and taoist is too weak without krivis.
Miko does look like a good option, but all we know about it so far is from data mining and that's very likely to change.
