Why the hell is not sewer and main instance not private? Boss respawns are 30min inside and you have to fight other groups inside. They instance every zone but not making it private in elite instances is crazy, it makes no sense.
Ditto, very needed. Boss respawn times + other groups = ruined PvE experience. I play on a PvP server yes, but even here, one should be able to go into an instance with five-six friends and get some items without having to fend off every Aquilonian and his mother.
