This IS an issue on every server thus far and it will get much worse if FC should ever implement server hops. I am sick and tired on not being able to even get a chance at a rare drop because some gay a$$ bunch of campers (most of the time the same ones) have either:
1. Parked their characters at the spawn and kill it everytime it reappears for hours and hours...
2. Have killed the spawn everytime for past several months and therefore know the exact time of the next respawn.
Funcom if you still give a slightest crap PLEASE I BEG YOU implement a rare spawn pick up timer like on Asheron's Call, where is the spawn time can be quite short, however the next time that a particular player can pick up that unique item is like 7 days or longer. This is the most effective way to control unique/rare spawns and make them at least plausible for 90% of your players to try.
