Seems like druid has some aspects with minor changes between live and ptr that were not listed in ptr patch notes. This is just based on the codex, so I don’t know yet how reliable it is, and I am unsure if they will come with season 4 patch or ended in the ptr build by mistake, but listing anyway the ones I noticed:
Aspect of calm breeze deals flat poison damage in addition to the old effect chance to reset spirit.
Aspect of might +1 sec to max duration 6s to 7s.
Rampaging werebeast from 5s max to 8s max.
Overcharged aspect +5% luckyhit chance from 20% to 25%.
Subterranean aspect +5% dmg from 20% to 25%.
Stampede from 26% to 30% max.
Aftershock +1% from 12% to 13%.
Voracious rage aspect added to druid (killing enemy with core skill refunds 30% of the cost).
Umbral from 4 to 6 spirit.
There were some small increases to minimum values as well, but those are not that interesting. At least Shockwave min value from 60% to 70% and blurred beast from 20% to 25%.
Also we had two new eye types and you can change hair/beard style and color in wardrobe.
