A topic came up here that there is no balance at all in 3, I'm telling you—you simply haven't played, so you don't know, stop shouting...
In 5, the balance is slowly evening out, not all at once as they say, so I think the further we go, the more balanced it will become; now regarding 10k, personally I tore them apart, the only problem is when a human plays against another human, then 10k is practically death!
Balance in 3..... hmmm tell me how Swamp on an XL map wins against Dungeon??? (this is just as an example, but there's plenty of imbalance there).
If one person has accumulated 10k skeletons against another, then the second person is an IDIOT, because to accumulate that many you need to clear the entire map and sit around accumulating more.... and a normal opponent won't let a Necromancer do that...
