I have nothing against it, in fact i think is pretty cool.
You only see CE/Tara, but you have no idea how hard is to form an Empire and rule everything.
The Empire circle formed by:
Cagilan (Main)
Tara (Satelite)
Coria (Buffer)
Strombran (Buffer)
Is not easy to achieve on BM, many have tried to form satellite realms but have failed (sorry for Dunnera, DOA and SOA fans*) It wasn't been cheap, all that was for a cost, the Empire main realm used to have 150 +/- nobles, after years of expansion they have now 60s. but their block is solid.
Not only that, the Empire also have Allies who will swing their way:
Tallerium (Brother in Arms)
Suville (New guy in the neighborhood)
All that takes great political skills and a good base of Loyalty, i respect that. i would not like to see them apart. Now the northern alliance have to rebuild and come back with a better plan in hand to start another Great Continent Wide War.
Keep it going!
ps:
*: East Continent
