Why are some dungeons below 90 closed?

This really bothers me. You guys have more than 10,000 people online at peak and yet we can't acess any of the vanilla dungeons such as Black Temple. I mean how hard can it be to just spawn the mob. Most people do this for acheiv/transmogs/memories, so they get one shot anyways, we don't care about mechanics.

It really does not speak well for one of the top private servers to introduce a new player into an experience in where some of these iconic vanilla dungeons are just plain DISABLED because they are "not endgame".

Because they are not scripted.

they won't just "spawn the mobs". they'll release them when they are scripted and working, endgame is priority, so don't hold your breathe waiting.
