guildmate of mine made approximately 1million plat (i know this as I monitored his bank) in th last 7 days by farming WoS. he tends to sit at the camp we call nwall on Cazic. it's on the north side of the wall and like 7 different named all pop there. He sits there on average about 4-5 hours a day playing his ranger (tanking/pulling, dps) and botting me while I'm at work. it's good aa's, and easy loot. Not sure if you need harmony to pull the stuff or not though
If you can keep all 7 spawns clear, you can rake in the cash via drops, runes, possible scoriae / slugworms / augs. I still think that 1 million plat is a bit excessive, but he wanted to horde cash before DoD goes live so he can buy spiffy trinkets heh! Course he did this when omens went live.. spent like 800k in augs within the first like... week of omens..
