Personally, I do not want some of them here in Mereholt or Barbiron. When I first entered Caergate at Level 23, these bullies would not leave me alone. I could not get further than the end of the first hallway. Ever. I finally completed an escort mission because there must have been 50 of us doing it at once.
I believe that I was wearing the kill me, please, sign. Although it appeared that Sentinels were most fond of me and my dogtags. Yes, if you are 27-29, let the people new to Caergate have some opportunity to play. I left there shortly after entering and made levels by repeatedly doing missions from the "vending machines" at levels 23-29 which takes time but is not as frustrating as being someone's punching bag on their home turf.
