Epic raid re spawn

Epic raid re spawn is 1h or something like that?

 

No

 

We killed for example Core, and he re spawned in ~30-60min.
Why?

 

And today, Zaken was killed, and he re spawned very fast.

 

So, nobody knows why epic raids re spawns almost like mobs?

 

the appearance of bosses at a fixed time; if you kill a boss before he arrives in about an hour, he will reborn again at a fixed time

 

And this fixed time is?

 

20:00-21:00 i guess

 

Hmmmm, so it is about once a day. And I hoped it is ~once a week :\
