Option 3: Open /who, check your lvl bracket (Eg: 40-43) and ask potential players if they wanna join you? after you do the flashpoint if they're good add them to your friend list, then the next time u'll have more players that you know that are good to play with.
result? good community.
because.. someone ninjas? /ignore them, u'll never catch them again in another flashpoint that you organize, which will be all of them.
u cant od that if lfd tool shares servers. if it didnt? i wouldnt oppose.
