Replace access to cultural retinues from wonders with "summon army" decision

[MemeWizard]

Describe your suggestion in full detail below:

Replace access to cultural retinues in some mod wonders with decision to summon an army

Because: 1 - AI don't know how to use retinues 2 - Not all players have "Legacy of Rome" that give access to retinues 3 - It useless to have cultural retinues without cultural bonuses anyway
