OK, this is trial and error based, but you can use this hack and CO Loader to get over the Guild Castle wall! You'll find that if you try to jump onto or over the wall, you'll start jumping and then suddenly you get jerked back and it lands you on the ground outside the wall. You'll notice, however, that sometimes you're over the wall before it jerks you back. What you have to do is try and D/C while jumping and at the moment that you're over the wall, it'll show you getting snapped back as usual, but when you log back in, you're standing on the wall! I tried this and kicked some ass. Everyone will just figure that you logged out inside the castle somewhere, so unless you do this more than once while the castle is closed, you're safe. People will bitch at you for logging inside the castle, but they have no way to know that you're cheating. On some servers where GW is disbalanced, they leave the gate open but protected, this is a good way to get in in safely in that case. They'll figure that you snuck in un-noticed somehow.
Sabbathin: Why is it a useless question? I don't know what a bandwidth controller is and would like it if someone would explain what it is and how to get it. Also, the no questions rule applies to making threads. For example, you can't post a thread saying "Where do I get a bandwidth controller?" but you can ask a question inside of the thread.
BTW, whether or not you use proper punctuation, "Whats the ponts with u doing useless questions?" is a question. Please leave moderation to the moderators, if they tell me not to ask any questions at all on this forum, I'll comply. It's silly not to allow any questions at all, for every bot/hack/exploit someone's going to have a question about how to use it.
