We're actually talking about creating a clan to help ensure high levels have fun too, but obviously that's a very tricky situation because we do not want to ruin anybody's gaming either.... tough to find the exact right way to implement it
As for the tunnels, it's not the same as the borders... again, forget the game for a second and pretend we're outside walking around. It is VERY unlikely that we would bump into a tower or castle before we saw it. However, now pretend we're down in some caves/tunnels. If we climb up a ladder and poke our head out, we have no warning about what's there until our eyes have line-of-sight (literally) with the guy aiming a cannon at us... However, he can see us when the tops of our heads emerge... he wins
Now, back to the game... the tunnels were designed to provide an extra entrance/exit for clans strong enough to maintain buildings by the entrances. Nobody needs to use them, so it's not taking anything away from their gaming experience. Additionally, it should allow more clans the ability to build on that map since having extra entrances (including entire left border now) means more buildings are needed to protect it all, which is more difficult for a single clan
About the "ruining game experience of others" I completely agree with you. As a game moderator, I think the two most important aspects of that are 1: ensure players follow the rules and 2: work to help players enjoy the game ... the only problem here is that some players enjoy the game by doing things which other players don't like. If they aren't specifically breaking any rules, it gets hard to walk the line between stopping him from ruining another players experience and ruining his myself, know what I mean? However, after saying that, I'll say again that I agree, we need to enforce that rule more swiftly
