In Retail WoW (and I’ve been playing since original Vanilla, btw), there is Dungeon Finder for everything but Mythics and N, H, M Raids. It works out fine. The only difference is you don’t have to spam the chat channel. There is minimal benefit to looking for a group on a chat channel. Most of the people still don’t talk much and there are still your hostile hardcores who need everything to go perfect or they throw fits like a 2 year old. THE ONLY difference, is that I don’t have to reach to them myself…it just happens.
