Eco-War is great! I do them as often as I can usualy. I think the key is a players patience. If you're going with strangers, people WILL act stupid. Personaly, I dont mind much. Sometimes it's really quite funny. And the exp item has helped me through a few tough spots. A few times now I've died, deleveled, and decided to just wait for the next eco-war to get the lvl back.
Anyways, if you're having troubles getting an eco-war together, just ignore the angry shouts. Usualy its someone with less patience who hates dealing with an alliance full of low levels making silly low lvl mistakes. If they really bother ya, blist em. No one needs that kind of negativity. :)
