Agree, it is easy.
A well-kitted archer can get to 105 in a matter of hours, especially if Abandon Camp is almost empty and you can run huge trains to your stacked archer for a couple of hours or so with an out of party tank. I know, because I've done it multiple times a day in order to get my +12 earring. Yes, I had other XP boosts, Dragon buff, helped some, too, I bought AC rechargers and it was during the current boosted vitality period. I levelled 13 characters to 105 over 2-3 days. I'm sure there are even faster ways to do the same.
If you don't have a stacked archer, the game allows you to have 3 accounts online at the same time. That's two average equipped archers assisting each other (get your macros set up properly) and one puller. All you need is to pick the right time to go to Abandon Camp and you will level relatively fast. No, two average geared archers don't measure up to one stacked archer. But they do XP faster than one archer solo. Just make sure the tank doesn't aggro more than you can handle. Start off in a small corner where crowd control is more manageable and you don't have to worry about archers' Mulitple Arrow spray accidently pulling more mobs than you can kill. As you gain levels you can move more toward center of room and pull more mobs if AC is empty.
