I don't see any reason why people can't enjoy content they were unable to do before for whatever reason. Who are you to judge others for enjoying you know, a game?
Went down there the other day to grab one of these since a buddy is leveling NIN... Still kinda cool to go pwn those mobs that gave you trouble at 75 :p (Yes, I knew you could solo @ 75 but i'm referring to the overall experience aka camping and competing)
I think it's also because no one really camps them anymore (at least not like they used to) so it's easier to get those items. ..plus...in the off chance you might still have a job that is a low enough level (to consider that particular item worthy) ^_^
i know, i killed other day on dnc while farming blizz 4 and 5. was an item i always wanted when we were 75 way back when, lol. i know there is better ammo/range now, but still a nice piece.
