Sorry if this is noob question and its not related to the Founder's Helm, which is the topic of choice these days...

When you defeat the Red Dragon, and fight the mobs that remain, are they endlessly spawning? I've fought for quite some while but players start leaving and i couldn't tell if there is an end to those Red Dragfon Lair mobs that support the Red Dragon.

Has any team stayed on to fight a long time and can you confirm whether they spawn indefinitely?

And if so, does the XP rate fighting there beat the Lost Valley spawns?

thx
