...i would like to see spells trigger the healing effect and maybe the withdraw, on units with second chance, like combats do.
On adopting religion
What do you think if we move adopting religion out of Priest guild into an early civilian tech?
The Priest guild is still there, you need it to build Pagan Temple, Temple District, Altars and Priests/High Priests. But, you can adopt a religion without it and gain benefits from its temple and miracles without the Priest guild.
Consider the Priest guild as the "institutionalised" version of the religion.
Try to prevent the holy city being given to a civilization that did not take the priest guild and make the ability to adopt a religion of your choice as the same tier of getting your third guild.
I think you mixed up the mechanics here.
To get a religion:
As it is: you need to adopt Priest guild.
Future plan: you need to research Ancient Chants, a tier 1 civilian tech cost 600 beakers (Barter is 300 beakers, for comparison).
To get holy city:
As it is: you need to adopt Priest guild, get a religion, then be the first to acquire second Sacred Knowledge by accumulating enough faith.
Future plan: you need to research Ancient Chants, get a religion then be the first to acquire third Sacred Knowledge. Theoretically, you can do this without adopting the Priest guild but it won't be practical. To make sure that you get the holy city, you need to adopt the Priest guild.
The future plan is not changing anything other than making Priest guild as an option, instead of an obligation. It's just like how the Magi Circle is: an option to those who want greater access to magic but you can play fine without it.
No, I did not ignore the mechanics. At all. I am stating that this requirement that you are putting up in the future plans is too early and should be later in the tree, specifically the same tier as the third guild tech.
Can I be any more clear?
What changes to the files are necessary to give heros the same chance to defend a stack as normal units?
It really bothers me, that I have these high-leveled guys and they are basically only useful for offense. A "true" hero should be the first to jump in to defend a city, not lingering in the back watching the garrison getting stomped.
