OMG! That's one of the most awesome things in GW! When your out in the field doing quests you can do all the gathering on one character AND you can use the same nods as your partner. No rushing to a nod or nod stealing if a mob is patrolling it. You work together to get to the nod and both get to farm/mine it.
I also like how in the field you can click on an item and send it directly to your bank by clicking on it. Also you always have a mailbox with you in your character tab. Save a lot of frustration.
yes especially at low levels when you don't have the extra bags. Your bank is also shared by all characters so it's easy to transfer lower level mats to alts.
