What is so "socializing" about spamming LFM BBQ ? If I want to socialize I talk to people Im mutually interested in, and I think non-problematic group finding is actually helping that, because it just means I get to "meet" more people than on general chat. I think they should implement server wide channels aswell easy finder for people who wants to be more efficient with their time spent ingame. That way those who want to just experience content have easy way to do so and people who prefer picking other party members according to their taste and preferences can use LFG channel.
