It would be ideal if Vyragosa / Time-Lost Proto Drake spawn every 8 hours to 24 hours, without doing the 'kill all rare elites in Northrend' method.
It is extremely hard to camp them than camping them in retail, because everytime the server crashes/restarts, the timer interrupts and they spawn instantly after server crashes/restarts, making it pointless to camp them.

Way back, they use to spawn every 4 hours then they changed to every 8 hours and then they changed again and now there is NO IDEA when they spawn, I've been camping them for ages.

Please think about it and thanks! :)
