As a host:
As a host AFK forest hunters invade me all the time, i sometimes get invaded by 5 different AFK phantoms in a row and I really hate it, its boring and personally i would rather get invaded and killed by the cheapest player in dark souls I dont know someone rocking a havel tank with an DMB buffed Great Club, most likely a hornet ring, using TWoP and then finishing me off with a 15 min spam of Dark Bead then get an AFK phantom just standing there.
As a hunter/red invader:
Gangers in the forest dont really bother me, im sure that just like me most people invade there just to fight gangers as beating someone in a 2v1 or a 3v1 is really rewarding. However i also enjoy when a fellow phantom invades and the game changes to a 2v2 saying that i do not really need to explain why it is irritating for them to be AFK.
Now what i do not understand is why people do this and why is it so common? I understand if someone went to the toilet for 5 minutes but getting invaded by multiple different hunters all of which are AFK is just stupid, what is it with people frequently being AFK with a Cat Covenant Ring on?
