FTE/Camp/Release Qs (non-raid)

[astrocreeper]

I've been looking through the rules on the forums and I'm left unsure what "engaged" means. I'm talking about random trash in random zones, not raid or even group content. Let's pretend we're talking about fire beetles in a newbie zone.

At which point is a mob engaged:

a) player is sitting down, mob spawns on top of him and starts beating on him
b) player's pet takes a swing but MISSES!
c) player stands up and casts either a stun/mez/root/fear/snare... it's RESISTED!
d) player swings and MISSES!
e) player's pet hits the mob
f) player lands stun/mez/root/fear/snare
g) player damages mob

Is it "a"? That's my guess but I'd like to hear from the experts.

On a related note, when is a mob back on the market? What if the player feigns or mem blurs?

Additionally, with roamers that spawn at static locations at static times in outdoor zones, these are generally considered FFA correct? Can a person sit at one spawn point and "claim" that spawn as a camp? If someone sits around at one beetle spawn point waiting for it, is it their camp or do they have to still FTE the fire beetle after it spawns?
