It's funny that you feel you get to say whether people should receive a tool that allows them to quickly and easily organise a flashpoint.
If you play on a server where every general chat request for a flashpoint is followed by instantaneous plea's for invites then congratulations.
For me, despite being on a server that is full most of the day, people's requests for groups tend to be greeted with, "can you please stop that *********** spam, nobody wants to play with you". (I hasten to add this is not aimed at me, but have seen it often enough.)
By the way, not only WoW operates an LFG, it is fairly common place.
I don't PvP, so should I campaign for PvP to be removed from the game as it doesn't agree with my playstyle?
