I'm not a fan of the CB type mods, although I do appreciate how the CB mod is split into sections.
I definitely like the nation mods and absolutely LOVE the worthy heroes mod and want to see further additions. I essentially play most of the game just to get a few SCs and nurture them along. I get REALLY bummed if one dies off
I'd like to see more national spells, and recruiting sites as they can definitely add flavor or flesh out weak spots.
I currently use:
CB Scales
Worthy Heroes - need more heroes!
Mythological pretenders
Militia and light cav buff - even though i rarely use the troops
Healing gods - non-recup pretenders suck
(I'd like to see all gods with recup in vanilla, and those with recup already get regen)
