I agree that OOTD needs to be different however it brings about a conflict from a lore perpective.
We have HRE being a proper civlization with economy and military well in place and then we have the OOTD which is a religious militant order composed of highly trained aristocrats and is essentially a professional military company.
OOTD in itself doesn’t have a leg to stand on to be it’s own civ or a variant civ. One of the only bits that makes it stand out and ties it back to HRE is that OOTD’s founder Sigismund becomes the Holy Roman Empire which essentially gives it a reason to have the HRE tech.
A strong argument in favor of this is the Jeanne d’Arc civ which has the exact same French tech and more, being a hero unit plus additional unique tech like Ordinance Company and Companion Equipment as well as the ability to spawn Jean’s champion units through the keep which allows players to play aggressive as well as do landgrab and defence.
OOTD on the otherhand has a burning weaknesses in that it is essentially a slower civ with the units while being strong cost too much so any unit lost whether a dragon villager or a military unit will hurt especially since they take longer to train as well.
Another weakness is that military units cost double meaning that you’ll have just about have half an army
and can’t force projectwhile the enemy players will always have more than you and will outlast you on attrition or wipe you out with ribaldquins, mangonels or nest of bees.
Another problem is attacks on 2 different fronts. It’s worse enough that you dont have a large army but now you have to split them in 2 who will most likely die.
The reason why I suggested those changes in my prior post is for the purpose of snowballing.
Marching drills is an age 2 tech that increases the speed of all infantry and prelates by 10%. This tech in particular will help when it comes to getting relics.
Additionally, if you have Aachen Chapel act as a church and be able to produce prelates by age 3 as well as upgrade them then you have a further snowball effect where when you go age 3 and choose Regnitz Cathedral which also can create prelates, then it means that you now have 2 chruch buildings automatically that can create prelates who will then partake in the relic rush as well as research upgrades.
This makes it so that you don’t need to build additional churches unless you wanted to though it will take 20 seconds.
While it is good to be able to add relics to Aachen Chapel for scaleability, HRE and OOTD do not have a competetive edge in a relic rush besides marching drills to be able to get relics in a timely manner in comparison to Russians which has their Warrior Monk on a horse and the Ayuubids who have athe dervish which is a monk on a camel who both in turn have better mobility which make marching drills a requirement.
Aachen Chapel having it’s mass inspire also effect military units will at least give a alternate way of playing the landmark either defensively or aggressively similar to keep based landmarks.
In terms of additional units, they can probably add in Sigismund as a hero unit which is contentious as per the feedback on Jean d’Arc.
The other is having a bombard unit as by the 14th and 15th century (which HRE and OOTD is a part of), a lot of civs get bombards by this point.
HRE specific ones are Pumhart von Steyr, Faule Mette and Galeazzesca Vittoriosa as an example.
The alternative is that all these upgrades should go to HRE as they have definitely been missing out for a while now.
