If u dont need it for ur main class/specc, jus always ask.
May i need for second specc/second gear or alt..
But i would never kick someone who needs after all have greeded.
I would beg him to ask in future..
Imo its stupid to even ask that question, since everyone has a bunch of companions, so what makes you think you should get it and not someone else? Thats just beyond me. I would never ever do something like that. Only once I just hit 400 biochem and wanted to craft that reusable rakata stuff and needed that Biometric Crystal Alloy, so I offered everyone payment if they passed. I would never expect them to pass for no compensation whatsoever. Thats just so darn selfish.
Its really beyond me how people can be so self-centered. But judging from my every day experience not only in-game but in real life too, I suppose most people actually are.
