One last thing frmo me then I'm out. I'm only writing it here, because you can argue that it has to do with the topic.
Gnomi - Main reason that most of players chose Edain, is diversity from original. Diversity containing buildings, units, heroes, spells and many many more. So it's wouldn't be wise to limit them to only this ones who's most useful, as you like.
Have I ever written that I would want to do those limits?
No.

I know that not everyone has my opinion and therefore I would never suggest such a thing. As I also tried to say, the amount of truops always depends on the game. I also play AoW and every faction has about 20 different units. It fits perfectly for that game and I'm happy for it: But every unit has a purpose and there is a reason why you should be unit A or unit B.
Concerning Edain:
In earlier times (until edain 2.2 or something like that) edain already had really good skins and modells, but it was more of a standard mod. Why? Well, we just added dozens of different units and dozens of abilities. You had about 5-10 troups in every barracks and there was nearly no difference between most of them. Then we started to think more about the units. We put some of those units in spells (and made them not buildable anymore).
The more we changed those things, the more people started to say that edain doesn't feel like a normal mod anymore, but more like a completely new game.
Of course it's important to have new designs and have more things in the game as in the vanilla game - that's one of the things which made edain famous. But edain also got so big, because we started thinking about different ways of integrating units, which helped us to intergate more designs, but still have everything easy to understand, suitable for new users (if you build a barracks and have 20 different units it's more irritating and even when the units are good, it's more difficult to get ued to the mod)
The same counts for
When we did this, suddenly edain got more and more famous and even though the game got older, we got fans much faster than before.

So you're right: People like edain for the diversity.
But this diversity exists and is less stressful if there is no overkill and you have the feeling that you know what you're doing and aren't unsure all the time what you should do.^^
So we will continue doing this:
Adding new things, but we won't just add them as normal units to have more units, but will always think about way to integrate them and give them clear and easy understandable duties (and differences to other troups) to help beginners fully understand and enjoy the game.
