I, to be honest, only like this one:
5. Remove or lower the timer for global chat. Make it the main chat. We all use it and theres not enough players here yet to need a 20 second delay.
The other ones are kinda tricky. The one with multiple clients is, while allowed, a bit against the spirit of the game. Same for 2. Hide roof doesn't interest me at all but it wouldn't bother me either. Zoom level I don't know anything about. For 6 I think it's good the way it is, and well yeah 7.. Just walk from Varrock or buy amulets until you can get into the heroes guild. No need to devalue content because you can't access it.
