What's the point in elite units?

[QuintusSertorius]

except that 2 dont always do a better job than 1. due to better morale, 1 elite can tie down enemy armies for longer in some cases than 2 regulars ever could. due to better endurance they can wear down the enemy longer on the flank in some cases than 2 regulars. etc. this is my experience atleast, and if you disagree, i guess thats where the discussion ends.

I do disagree, because that isn't my experience. Elites are rarely much better at doing the same job, and they certainly aren't better than two regular units at doing it. Two units of Hoplitai will hold a line much more effectively than one of Hypaspistai, not least because one can pin and the other flank. Especially when you have the force multiplier of your own cavalry, doing the unit-breaking from the rear added into the mix.

The better morale is often irrelevant compared to the impact the general is having, and the difference between 11/12 (the usual morale of regulars) and 15 (usual morale of elites) not anywhere near as important as between 8-10 (usual levy morale) and 12.

sigh, you dont get the concept of cost-effectiveness.

No, clearly you don't. Levies are an irrelevance since they are not capable of doing the same job. Whereas elites are only at best 25% better than regulars stats-wise, for double the price.

The only economy elites are providing is in taking up less slots in a 20-unit stack than the equivalent cost in regulars.
