I am going to throw my two cents into this ring as well, I find it incredibly frustrating to have to disable this mod whenever I want to modify my Righteous Oathsworn faction that also uses Relentless Crusaders. I would say that Shock or Polearm would make more sense than Shock and Shield. If you would like to here my reasoning I would be happy to provide it, the reason I am not providing it now is because I don't want to bloat this message with something you don't want to read.

Echoing the sentiments of Lemonz a little bit but would it be possible to get some sort of compromise with Relentless Crusaders?

Since having the option limited for certain cultures compared to vanilla does hurt a little bit but the rest of the changes are rather nice for society trait options in general.

Why Choses Destroyers doesn't get no imperium penalty from unjust war?

This makes relentless crusaders incompatible with oathsworn, which kinda sucks for righteousness builds

Just a thought - why not a shock or polearm unit? ^^

Shock seems kind of a no-brainer for Relentless Crusaders. Not to mention that makes it a mirror of Scions of Evil which is appropriate

Shield or Shock for Relentless? What about Shield or Polearm so that Oathsworn and Reavers can benefit from the starting bonus too?
