You do understand that Bristugo is a place were players of ALL levels pass through and as such it is a good place to hold these events, but also in towns like Aughundell, Harro, ect. I don't care if all these attacks happen in Bristugo, but provide the low level players to take an alternate route to their destinations. I have tried to travel around not going to Bristugo from Last Stand, but whatever route you take with the portals you always pass that place. The same goes for Scorpions Island or Abandoned Island.
The only players who survive an assault while porting into Bristugo are those with loadingscreen off.
