1. Everyone and their brother is in some pretty crappy gear at this point as it's just barely the begining of the Xpac.

2. Multiboxing takes Paitence. It takes time to get your group all geared up, macros/scripts/keybindings setup, and experience to know how to handle your followers.

3. Jumping straight into Heroics the moment you hit 80 in nothing more than quest greens/blues is a bad idea whether you're boxing or not.

4. Multiboxing IS NOT for everyone! and there is nothing wrong with that. TBH there's been several times I thought about just saying forget it, especially when I'm frustrated by content. However I just keep a positive attitude, practice my encounters more, gear up more if necessary, and eventually I make progression.
