AI factions not taking initiative to attack the playing faction aka Passive AI

[Chola_Kingdom]

am i missing something here?, AI don't have enough fund to attack me at all?, some of the Ai are willing to declare war on the player faction, but not trying to take war initiative over.. for example when i play as Rome or Carthage, or any other faction and expand my territory with 3 provinces under my control AI seems to ask for non aggression than attacking me or warn me of my aggressive expansion or my influences... kinda feels boring without a challenge. this problem occurs with All the difficulties..
if im not alone in this, can we get a fix on this issue?
please put some economic challenge on the legendary or Very hard as well.
Senate orders... could use some senate system on both Carthage and Rome. secure promotion could use more effectively if we have senate system imho.
