Well Darth, let me show a comparsion:

Old: you had 2 big heroes and the rest delivered armies between the two (and probably a middle-level one clearing mines and other resources).
New: you have 1 big hero and the rest delivers army between the hero and the border-cities when not capturing mines (and probably a middle-level one clearing mines and other resources).

Old: you divided troops between your heroes and cities.
New: you have one immense transported army and a central creature-pool.

Old: you could attack the town, OR hunger out the opponent.
New: you can only attack towns.
With the new creature-pool system the one with more cities will be the victor (if that side simply sits back can never be destroyed if (s)he buys army only just before being attacked).
Or hear the thought of the new player: "Oh, in next round i'll buy that 1000 archangels, as I'll conquer that other town with all of its mines, and THAT will be an incrise in sallary."

Old: each side had to overwatch a kingdom.
New: you just have to keep one eye on the cities.

Old: conquering a town ment SOME rise in produce and armies.
New: conquering a town means IMMENS rise in your produces (and a lot taken away from the opponent), and cuts out the chance to gather spare-troops from war-camps while hurring back to re-capture.
