So this happened to me at Badlands, after 3days of searching for rare spawn "Broken Tooth"
Finally found it, got it aggroed to me and tagged and this hunter appears to tame it when I'm just about trap the cat. I told him "NO! I was here first", and I started attacking it, trying somehow interrupt his tame. When he tolds me "please dont kill it, I will give you 10g for it" When im like "Ok with that" Well he gets it tamed and after that he just tells me "Fuck you" and runs away.
The name of this scammer ninja rat is "Plmpslap" (i written with L like PLmpslap")
He got already Gkicked after this from his previous guild and I dont recommend anyone to invite that rat to any guild now on. Neither to group with him or run any instance with this scammer. Better you to /ignore this rat so you won't get in touch with this toxic player and hopefully won't get scammed by him.
