I'm new to Rome 2 and DeI.
1) I have to keep a sizable force on hand to play whack-a-mole with rebel armies, which is preventing me from building up a bank/invading the mainland.
I'm researching sewer-related tech so i can eventually build sewers, but its slow going, 20ish turns id have to say before I can expect sewers in my cities. And once they're up, I'm not really sure if they'll keep squalor down meaningfully for a signficant period of time.
2) I'm also receiving major penalty from Raiding. I'm not listed as being at war with anyone except Slaves, and I don't see any enemy units at all on my map (some sea trade routes are not fully visible though). How do I deal with Raiding?
3) In Camulodunon, I need 7 surplus population before I can expand. How do I find out what my CURRENT surplus population is?
