Geez... yeah, it's kinda common for it to happen now, when you're just hitting lvl50 with your first job. People are just too used swimming in memoquartz and can't understand that you'll need a bit of time to trade for a "proper" gear.

I was accompanying a friend to help him do his first lvl50 dungeons lately and people were always complaining about his HPs and ilvl50-70...

Don't let it get to you. It is a laughable behaviour, so you should just laugh it off.
