Looks promising.
Just one thing to mention: nearly half of my time is spent on the big map, so it won't be inappropriate to add more things in the legion battle. The game time is nearly half to half on both RPG and grand strategy side, but the content of two sides are unbalenced.
If devs really want to focus on RPG side and keep the legion battle simple, just reduce the region and add more story quest. Comparing to Viking, Rome in current state lacks interesting quests and story. Fixing this will make the game time lean to the RPG side.
Or makes one more step on the legion battle - give it a bit more complexity. Maybe a small card game like gwent will give players both playability and grand battle atmosphere. So that both RPG and grand strategy side are pretty much equally fun, just match their game time.
