Visceril, of the Sixty Thieves, had lately the initiative to organize battleground premades inviting people from RP Guilds to PvP. Even if not full team, it still might stand a better chance to be succesful than random teams. We are gathering on a custom channel, and take it from there.
If you orcs are interested, please feel free to /join dailypremade, or poke Visceril or me online.
