leveling in outland is really easy because of the tons of quests
available. you could easily level to 63 in hellfire peninsula alone
doing all the quests and the 2 5men instance a few times.
as for the 5k gold... there's nothing to stop him from already
having 5k worth of gold before tbc isn't it? it doesnt mean he made
the 6k needed for the epic mount in outland alone.
and in case you want to ask... i'm 65 now, but got the exp 3 days
after launch. i maintained about 1 level a day, but i still had
time to wander around doing nothing, especially when i reach new
cities. imagine how fast it can take if a person is focused on
simply levelling to 70 alone?
