I can duo pretty well, the only thing is having to sit down and med, but that's fine because then I can do other things while I med back to full.
I don't get hit often, since I pull with tash while rooting with my wizard, then ensnare and chain nukes on both characters, and I use hasted enchanter pet too which is fun. If I charm, I just have to deal with a few hits when Charm breaks, then I can heal myself pretty quickly with 2 characters using Bind Wounds. I like to get hit though to train my defense and dodge skills. I have bind wound up somewhere between 50 and 60 and it heals me 10% health a pop, so when I use both characters thats 20% per bind wound, no need for troll illusion, I simply heal that fast and training Bind Wound is a good thing
The most important thing for me when I duo and especially duo and charm, is to make sure that I snare the beasts I'm killing, for when Charm breaks, I only have 1 beast I need to deal with, wizard just roots the one I'm killing (wiz has most agro) while enchanter just runs back to stun or root then re-tash and re-charm.
I have not duo'd often throught my first 47 levels, but I know I can duo decently, I've done gnolls in eastern badlands to gather 40 pelts, and for my starfall quests. Grouping is really where it's at, way faster
I'll be honest, days like last night when I cant find group, I'm not worried, I do other things, I'd rather group for experience, last night was the first time I couldnt find someone to group with but I didn't try really hard, I just took that time to wash dishes and stuff finally, lol
