I think it is more about people's expectations from the game.
For me this game has
- An Awesome melee combat (if we disregard lame instastabs and macro-like feints)
- An Excellent teamplay game with many elements
- A Marvelous competition feeling, besting your opponent, being the strongest warrior etc.
- A Great combat system in general, with many possibilities
- EU_1 : Pleases me with the 2, 3, 4
- EU_2 : Pleases me with the 1, 4
- EU_3 : Pleases me with the 1, 3
- EU_7 : Pleases me with the 2
It's all up to my current mood, in which server I want to play in. I don't enjoy EU1 less when there are many ranged, cav or whatever is around. It is just a different scenario, different possibilities. People try to please their every needs with the same server (EU_1) maybe? That's why we have different gamemodes.
Maybe I'm the minority, but I enjoy it when there are some decent archers or cav around in EU_1. Nothing fills me up with more adrenaline when me and a few of my teammates try to deal with many cav at the same time, just an example.
