It's because about 1500 players play iEra. Lets say 500 of them are newbies, and barely know how to play, or they are just players that don't want to apply, or they are kind of new to Graal, but not so much a newbie. So there is 1000 left. All the 1000 players send in that application, all to 1 email. iEra only has a few people reading the applications, probably 3-4 people, reading 1000 applications. On iEra, the 3-4 Staff members can just look around, or watch people they think are fit to be a PR, and they just have to watch their actions, instead of reading 1000 applications.
