Ahh... You love to keep showing how master you are in this game, don't you? If you attack a city with range unit you get 3 exp. With MT (+50%) and Keshik bonus (+50%) makes it 12 exp in a turn... After reading this I think no point to answer rest... I'm playing this game for years, played almost 1000h and never met people who prefer CA over Keshik... Neither for MP nor SP. G'day to you as well.
