FYI if he tags the mobs and you kill it you both get rewards(if you deal enough damage). if you tagged it and he proceeds to kill it, you both get rewards(assuming his lvl 50 deals enough damage to keep up with your lvl 20).

This thread seems to me like you were the jerk/troll/noob. Maybe next time, talk to people? you are playing an MMO with people after all.

I was farming for aldgoat skins while leveling my 15 Archer, and asked people killing them, some said they were farming some said just exp, half of my leather I got from people getting exp (for free), cutting my farming time in half. Other farmers just needed to sell so I told them I could buy then and there cheaper, saving 30% in cost. And crafters alike only needed NQ I was working on HQ turn ins and I traded 2 NQ for 1 HQ. Just by talking, shouting, all in under a few hours I had over 200 HQ skins and 400+ NQ's , and I wasn't even farming skins anymore, I had switched to miner and was getting Alumen.

The thing is learn to work with people. I will admit i had some people not respond at all, or just be like "no" when i asked what they were killing goats for, but you can't win them all.
