alright then. i've just been to all capital cities and these are the locations that seem reasonable to do.
first up is Black Citadel. ruins of rin waypoint.
pro: no one goes here. like ever.
con: high density of passive mobs and npc's. they dont talk but still.
next up is junker's waypoint.
still a lot of npc's but in lesser size then ruins of rin. also still no other players here.
now two from Hoelbrak. both are near hero's compass waypoint. first one is the waypoint itself and the next is in the icefield behind it.
pro: no one goes here. and no npc's to speak of.
cons: other then personal taste none so far.
next up we have divinity's reach.
not sure if i should put this up here because its not that good of a spot but something to look at anyway. palace waypoint.
next we have grenth waypoint.
pro: nothing here so no people as well.
con: map chat can become a slight problem.
last up we have rata sum.
only place i could think of would be incubation waypoint.
pro: remote so no reason to go there. no map chat to speak of.
con: remote. might be hard to get to if you dont know how.
well thats it for me. tell me ideas or post your own. you decide.
