To the poster who was asking how to tank and heal an instance, if you use two computers to box its a bit easier. I dual-box with two computers, and have tanked and healed with success. I have my laptop next to my desktop, and I keep a mouse for each right next to each other. So when I'm tanking and healing, I control the tank by spamming buttons on my desktop's keyboard, and then I use the laptop mouse to control my Healbot mod. It makes it pretty easy to tank and heal because the actions you do to do each role are so different, you don't get them mixed up. Also, healing with Healbot makes it so you don't have to target a party member first (which would be a headache imo). If you happen to dual-box with two computers, I hope this helps =D

Also, my fail comes thanks to the fact I've been PvP'ing a lot lately with my dual mages. I decided to do some 2v2 arenas, and I've had several rounds end with a big L because my secondary mage never picked up my mains target, so she just stood there and watched! I kept thinking 'Geez, I must look like a complete idiot...' Other than that, I've tried to do the falling death over cliffs, but I tend to hit ice block before I go splat =D
