My main is currently Bokor2 > Diev1 > Oracle > PD. It’s okay so far, but people say PD2 is where things get really fun with the build, mainly because of Plague Vapors. Pandemic is also very strong. Good build for solo.
My other alt is Krivis going Taoist. Still not sure what filler classes to pick either. Was thinking of Priest 2 or Priest 3 and full resetting into SPR build for lols. xD But I may go for Krivis3 > Priest2/Druid2 > Taoist. Priest/Miko path is definitely the more “support” choice, while as Druid you boost your overall DPS. However, as people have mentioned, playing Taoist seems very… expensive. 
Bokor/Diev/PD path: more sustain, passive damage via dots/debuffs, more skills to use and weave in. Great AoE especially with better Pandemic.
KrivisTaoist: nuke nuke nuke nuke nuke nuke. Bad farmer/sustain. Great single target DPS if you build specifically for it. Can get expensive to play.
