the thing is... for example, when I play a Romani campaign and start campaigning against the Gauls I get to fight a few (2-3) strong armies, they include spears, plenty of swords, Gaesatae, Solduros, some of those druids... fun stuff... I defeat these 3 armies and continue campaigning. Now, if I just rush over them now, what do you expect? They throw plenty of levies against me, spearmen of course, that's actually to some extent, historically accurate. If the standing soldiers of a nation/people were defeated and killed/captured, what do you expect? Where should new elites come from, in reality? They can't come out of nowhere, so if a people like the Gauls isn't ready to submit after their standing or elite armies are defeated they would raise those farmers, workers, etc. and send them to battle with a spear, which is relatively cost effective and it's all you can do, if your enemy doesn't give you room to breathe...

Now, I'm not saying the recruitment system of EB I is perfect, it has major flaws (most of them coming of the RTW engine) but it's not THAT bad and big armies of levies coming from a practically defeated foe is actually historically more accurate than elite spam stacks ;) - and with the possibilities of M2TW it should get better, so let's be positive :)
