Kunark is going to have a lot of people racing to lock down certain mobs and camps for platinum loot. It will be interesting to see if we get those swarms of level 30-50 characters leveling up in the kunark zones, it really depends on how many people keep playing the game that aren't pegged at 50. KC and Seb will be jammin thats for sure. People will go camp key mobs day 1 and also the bind clicky mob for the duration.
