To echo what I said on Discord: We've already considered all the PRC content and decided against implementing it here. We may at some point in the future implement some of the same things they have implemented, but we'll do so ourselves and in a way that ties in with our existing systems and custom content. If you have specific suggestions, feel free to make them.
I knew it, but the prc is big and diverse and particular implementations can help this server to be a better one. For example, the actions of climb and jump, could be added to climb the walls of vallaki being a outlaw ot climb a mountain for hunt thing in the highness to use the advantage.
A suggestion: Why not take the character builder module you've made and make it into an actual playable module? Not anything big, but just an area or two. Then you can implement some of the things in it that you think would improve the server to demonstrate how they would work?
Finally, offer to share your code with Devs.
That way, what you are suggesting is not a bunch of work for someone else to do--as opposed to work they'd rather be doing. Because POTM is done on a volunteer basis, inevitably the Team is going to work mostly on whatever interests them at the moment. They will work on their vision, so it's up to you to get behind your own vision.
If you do good work, though, perhaps you would be encouraged to become a Dev yourself.
If you don't yet know how to do these things, then perhaps you could join with this group:
