Of course, Sangwa. I actually belong to a crafting guild, the CotC. However, there is a mercenary guild on the system that has been active for about a year now, and maybe longer. And they do not allow their members to act in a overtly rude or aggressive manner towards other players, which seems to be condoned in this guild.
Of course the alignments don't count in Planeshift. However, the players continue to describe themselves using the traditional alignment system. As long as players continue to describe themselves and their guilds in this manner, it will be apropos to discussion about these issues. I don't agree with using alignments either, however, I would not copy an existing guild were I to make one myself, as there is a rich field for interpretation and ideas within the system and settings. As you yourself well know.
They might as well have called themselves the 'Dragon Mercenaries'. As far as I am concerned we can have as many mercenary guilds as the players wish to create. You are correct, outside of the settings work on the game, there is really nothing original. But there is especially nothing original about racist guilds, and griefers really bother me. Peace.
[I should mention that it was my experience since I started that lead me to say about a year for the other mercenary guild. Honestly, their founder was around for quite a while, possibly since A.B. and may have had it secret, it could be older... But this was my assumption, no one in that guild told me this. Thank you]
