Both locations are heavily farmed, and with the advent of the new warlock quests in Felwood that happen to be very close to the elemental area, the small area is often packed with 3 or more players competing for the spawns in the relatively small world of warcraft gold area. The Plaguelands areas are also farmed, but instead of one there are two, and the other one is significantly large which allows for many players to grind there without stepping on each other’’s toes too much.
