My main issue with the Timeless Isle rare spawns is that i do not know when they will respawn - and in the case of randomly spawned rares, i got no idea where they have spawned.
I tried using RareCoordinator addon but it just does not show any data reliably - a lot of times it won't show where the rare is, sometimes it even fails to notice that a rare spawned, it does not show any respawn times of the rares...
I am using the Rare Spawn Overlay addon, it is basically just a map (M) overlay that displays approximately where the rares tend to spawn, but nothing else.
And the NPCScan addon is horribly out of date, with it's last update being almost a year old (october 2012), so it is useless.

However i do see people in the chat reliably knowing (and then letting the rest know) when the rares will be respawning - so there surely must be an addon that does this properly, but no one is answering when i ask about it in the chat.
So do you fellas know what addon can display the accurate respawn times of various rares on the Timeless isle?
