Another issued I haven't seen mentioned, overcrowding in D1, unless it is unlimited in population. You are in D3, the LFG you want is in D1. When you try to zone there, you can't, because it is full.
People mention traders, guild recruiters, etc., spamming all chat, But what about people only working on party, drunk, and sweets titles, taking up space for people wanting to zone in to join their group. Maybe find away to discourage this activity, unless actually LFG. Also to discourage people zoning in, not logging off, then going afk for an extended period of time, disconnect them after X amount of time of no activity. I mean those that go to work, school, or bed without logging off.
Just other possible issues to deal with.

I guess the simple solution for this would be to expand party search and the chat options to suit every possibility, and have Tyrian/Canthan/Elonian districts.
