1. The COAs and COA designer (presently designing COAs is one sided undesirably image-less)
2. The historical characters
3. The cardinal trait (as popes named many more than ones in game)
4. Something similar to the templar system where your character can join an order of chivalry
5. Historical reform decisions
6. Peerage of England system
7. Ability to create a holy order
8. Holy war was nice
*Not TPATT but it would be nice if later gen dynasties like Medici, Borgia etc....
Thank god the guys from SWMH stuck around cause no one makes better maps than them.
1. The mod creator of SWMH has been bitten by the CoA bug lately, he has been making a lot of new CoA's for the next SWMH release. But he will not be using TPATT's CoA's. He's just going for historical accuracy, like we always are.
Other than that you need to talk to Arko when it concerns CoA changes.
2. We are always trying to add historical characters for SWMH at least and i suspect that Cybr does the same for VIET. In SWMH we usually add historical characters when we do an overhaul of a specific region. I have started research for the overhaul of Anatolia and Greece for example and if i find important historic characters that are missing from the game i will of course add them. We don't specifically go through the old TPATT files during this process, because verifying our data from scholarly work is more important, but if you know of historical personalities who are not currently in the game that you would like to see added you are always more than welcome to suggest them to the SWMH team.
3. The cardinal traits sounds like VIET territory to me if Cybr is interested in adding it. Or potentially something that Calantyr can add to his thematic additions.
4. Calantyr has already created a sub-mod that you can run alongside HIP that adds parts of, or all of the templar system

5. It's been too long since i've even looked at the TPATT files, so you'll need to elaborate on that one.
6. Again, this sounds like something that belongs in VIET or in a submod (Calantyr again)
7. I think that this would be a bit low on the priority list to be honest.
8. How did the Holy War CB in TPATT differ from the HIP equivalent
Oh and one last thing. The team usually have their own ideas and plans on how to develop the different modules, which they are working on continously. And borrowing from other mods have always been way down on the priority list. You'll need to do a lot of convincing as to why it would be so great to implement the things in question if you want them to put the things that they are doing already on hold or to do things radically different (which it sounds like you're asking Arko to do)
