Why they just can't die?

[Rahl]

The druidic healing trait has nothing to do with Ynys-Duwall, it is tied to temples of fun and temples of governors (Llew and Andraste for Casse)
The trait from Ynys-Duwall affects law, troop morale and influence, not healing.

I know that.
But the region starts with the highest School-building of the celts and I build everything else that gives good traits there, including a big temple of Llew, so it produced my best druids.
Ynys-Duwall should actuelly help boosting druidic skills, the trait description says so. I know it doesn't, probably because the team hadn't the time do implement this, like many other traits and triggers.
