I was always fond of the idea of having two seperate continents, NA and EU, so that way everyone is still on the same map and can trade, etc. But prevents issues like deciding who fights on which server. If someone really wants to go and invade, they could.
But a bigger map, eh maybe, it really wouldn't change much, if anything. The largest clans would still hold the largest amount of territory. I know someone wanted to give smaller clans special bonuses to compete with larger clans but that is just stupid.
And a definite no to turning the strategus map into anything based off of Earth.
