I have 42 Mules parked at every possible chest spawn in all lvl 20-25 zones. I've looted over 400 chests.
I've been doing this almost daily for about... six months now.
I've gotten every possible drop you can get MULTIPLE times. Still no Drakewing Bands.
Srsly THIS > . < close to just leaving MMOs in general, that's how sick of "pseudo-RNG" I truly am.
I've had this problem on every toon I've ever rolled, btw, and yes I've seen others get DWB but I guess I'm that other guy.
I used to enjoy not always getting what I wanted, but when you spend 20+ hours placing that many mules and then put in HUNDREDS of hours running them from GY back to their body every 3-5 days, etc, you will lose interest in this game so fast, I log in and don't even want to play anymore, not saying that chest farming ruined it for me, but, ya when you give and give and get nothing back, it's hard to keep giving.
GL getting them tho : ) Hope you do better than I have so far... (yes I'll probably continue trying, and then when I do get them, how much you wanna bet I won't even want to rogue anymore....)
