It's high time someone raised a flag on this crap.
I get real tired of spending hours an I mean like a whole day trying to camp/farm ONE single NM an what do I get? some chump who logs in either a moment before or right as or even just milliseconds after the NM spawns, then they claim it.. an they logout.
DO SOMETHING ABOUT THIS!!!!!
Force them to have to wait 15min before they can attack a notorious monster!
Don't just let them login an take stuff, they have to be doing something to know this info without being in the game. This is the only way to stop them.
