Dude. Make a toon, rush him to 70, get math q from a friend. Run T6 chests until you're geared. I play HC exclusively, m6 DH works for me, set traps and hide = my survival strategy. In the guides section there is an excellent thread on the cold DH, you should read it. I bot T6 on HC constantly with an m6 cold DH, stock settings, DB right out of the box, no problem, so can you. Doesn't take long, maybe a week or two..
There's no shame in botting T1 in HC, there's really no reason to bot a higher lvl, you'll get T6 items from chest runs. You need to learn the basic survival strategies before botting T6 will serve you (ie: you'll keep loosing your toons)..
I always have many backup toons, I'm always ready to loose a toon or two. I have a sader a WD and a barb who bot T6 no problem as well. I've never had luck with my wiz or monk, T4 tops..
I play all games HC, it's what I'm used to, once the idea of never dying gets ingrained, it becomes easier.. It's probably more difficult to switch back and forth from HC to SC..
Anyways, GL..
