I'm sure a lot of people do what you just explained. However, with you directing it toward me, I'd like to say I do the exact opposite. I go in decent gear and the few times that I have encountered pkers, I stay and fight. Most the time I'm tb'd anyway, so might as well stand and deliver! mate. Regardless though, it's the wilderness, what you're complaining about is equal to the kids that say "Wahhh, they pk'd me at revs, I was just trying to get loot!"
As it's obviously known people can kill you and take your shit in the wildy..
It's a double-edged sword. Kids cry when they get killed in the wildy, you laugh. They choose bring shitty gear and you kill them, you get nothing, and you cry while they brush it off and re-gear, etc.
