Blizzard, however, disagrees. Neth says clearly that the devs are standing behind the new system, and that no matter how much players ask for it, the old LFG channel ain't coming back. In fact, she even asks that players who don't want to use the LFG system use it anyway and give feedback on how to make it better.
I'm not sure that's going to happen-- it's Blizzard's responsibility to get creative about solutions, not the players'. But in the meantime, lots of players have gotten creative anyway, and if you "/join lookingforgroup" on almost any server, you'll find a close enough approximation of what the LFG channel used to be. Until Blizzard fixes their interface and actually gets something in place that finds me the group I want doing exactly what I want, you can meet me there.
