I'm sorry to hear that. I too have always helped out newbies and those in need without asking for anything in return. Usually I just get the kill in and take a portal back to town without checking the loot. Whatever drops I let the person I'm helping take it. It doesn't bother me much if they get a rare unique cus it's their luck.
No need to go to the dark side. You could if you want to, no one can stop you. But I still believe in being the good guy. Recently it's paid off.
Got this while soloing a level 66 map from breaking a pot:
You'll probably not find Shavs; you usually never find what you're looking for, but you'll probably stumble upon a Mjolner, Windripper, or even a mirror unexpectedly. Have faith in being the good guy. (Don't check the loot if you're helping someone out--get in, get out, good deed done, +1 karma).
EW, a troll mantle, throw it away! :P
Why would anyone wear that +1 fire gems and crit of are much better
