Fill up kingdoms faster. Way too many kingdoms with 15ish provinces. At least fill the kingdoms to 20 and then let the last 5 be through invitations.
Don't like the merge conquest & trad march idea, cuz then intel wouldn't even be needed.
Strengthen Dark Elves. One way would be to change the way Tree of Gold works. Have ToG not be based on their current income but on something else (so much per acre or per population) that way it can be useful even at a high draft.
One more thing i forgot. Regarding the dragons, make them stay for a minimum time (12 hours?) after that time they can be killed like normal. Reason being is that the only good dragon is the Ruby. Thats the only offensive dragon, you can time your dragon and send it with your wave. The rest of the dragons rely on your opponent NOT killing it.
