Well I'm trying to gear up my alts by killing the world bosses out in the world but usually they aren't even there. I'm not sure if I miss them just by a couple of minutes or if they take hours to respawn.
What are the Respawn timers on The T17 World bosses? (Drov and Tarlna)
Drov and Tarlna respawn quickly - "about 15 minutes" seems to be the most quoted respawn time.
However, only one of those two bosses will be active at any time! On days that Drov is respawning, Tarlna cannot be found, and vice versa.
Tip: Check whether LFR shows an existing raid for one of those bosses and, if so, join that raid.
