Say you dont have a rogue/BS/engineering and need someone to open your lockboxes.
Now we all know some woudl do it for free out of kindness, but most rogues(at least on my server charge)
and besides, the chances of opening them free have been growing slim since most rogues get asked literally 10-30 times a day and I can imagine they get aggravated.
Anyways, find a rogue that is in a guild you want to start with the lines like
''hey bro could you do me a favor?''
The response will most likely be , ok what is it
then go
'' Hey could you open a couple of lockboxes, I got an alt in your guild ''
Since he is in a guild he will most likely open it,
The only sucky part I could think of is some private 5-7 member guilds that know each other and their alts but ive never had it happen
