That is strange indeed

I did improve the odds of the AI accepting peace the longer a war takes, but I've double checked and none of my campaign changes should have any affect on the AI's willingness to offer/accept becoming client states. Perhaps this is an issue that originates with DeI, or its just the incompetent campaign AI playing up.
Thanks!
Since the mod is for the english version, I assume the text-based changes at least won't work on the german version.
You can find it in the Aeim_special_ability_phases table. Version 1.3 had a 30 second duration, for 1.3.1 I had the duration increased to 45 second to compensate for the slightly lower reload speed. I'm open to suggestions if that is too long.
High praise, thank you!
Yes that is working as designed. All hoplite-style units have way too much survivability in DeI, and in the first version of this mod using the normal DeI stats units like triarii were pretty much immortal in melee because of this. All hoplites have been completely overhauled stat-wise, most notably melee defense has been severely reduced. Note however that the ingame tooltip stats do not accurately represent the true stats: Hastati have 13 melee defense, Principes have 14 melee defense, and Triarii have 11 melee defense in my submod.
You should still find them the best defensive roman unit however, holding the line longer than any other pre-marian roman unit.
