Would you consider adding a factionwide -% servile unrest and maybe a reduce slave population decline skill for governors or add it to an existing governor skill?(like political reformer or maybe adept tradesman), I was playing a co-op campaign and was doing just as well as my partner but his settlements were far less angry at him because he was playing sparta and has the -25% servile unrest bonus while getting a 44% slave bonus instead of constantly having to cull 20 flag armies with rank 4 units all the time like I do. I consider removing servile unrest to be going too far but something like a governor who specializes in social reforms to reduce slave unrest or maybe a slave master skill that increases wealth generated from slaves as well as reduce decline and servile unrest or something. Personally I hope you consider just tying it with political reformer because if you use it on as many governors as I do, you completely run out of research at some point and the skill becomes redundant aside from the corruption reduction.
