welcome onboard

dual boxing two chars, you would be able to do quest even groupquest depending a bite there are some group quests that are hard to do with less then 5 char, but can allways skip those.

taking down 5 mans instanser with 2 char, now that seems like a unpleasent way to spend a afternoon
but if you configure one of them to be a healer and the other a tank, getting 3 other dps to fill your party should be easy enough
but then i migth have selected a pally for tank and priest or shammy for healer,

anyway check out the rest of the forum, its so much information and knowlegde here that it may take you weeks to "grind" trougth all on the info hehe
