System rotation target ?

[Troy]

The most plausible solution I'd support is that written by baalzy: zero to minimal variance with server resets every ~month.

If I were in charge I'd just have the mobs spawn all at once every 25 hours with 1/7th or 1/3rd the loot depending on their original spawn time. Would promote smaller guilds or at least smaller raid forces, making things much more challenging.
