Boss spawn timers should be dynamic based on how many players are in the zone when it was last killed. With that, 1 minute is far to short for a respawn.
Same thing with the respawn of anything quest related. Having them on a dynamic timer makes events and zone launches less annoying.
5 minutes is just enough.
Lower would make it a farm spot.
Longer would be boring.
There are a lot of threads about this. Anecdotally, the Southern Elsweyr bosses seem to take an extra long for me. No, I haven't timed them. Based on all the threads, it seems like it's generally agreed that World Boss spawns are either five or ten minutes (I couldn't find an "official" source), but even that range is not always everyone's experience. I am not sure if this is due to bugs or variance in zones.

I also got that a few times: there were so many players present when the boss spawned (because it took too long to spawn) that I missed out on loot because my share of the damage wasn't high enough. Reducing the respawn times would mitigate this problem.during the event i killed 9 world bosses in southern elsweyr. a few times, i arrived just as the boss died and each time it took 10 minutes to respawn. there were between 10 and 20 other players there each time. faster respawn times, like every 5 minutes, would mean more people getting loot from the boss. the thing where only the top 12 damage dealers getting loot sucks, very poor for tanks and heals as well as newer players.
