As I tried to explain to Kaver, I'm not arguing for the inclusion of LFR or any other automatic matchmaking systems, or instant teleports to the dungeon. I actually agree, within the context of Vanilla/Classic, that LFR and auto-matchmaking is detrimental.
However, a MANUAL tool to form groups does not have the same detrimental effects or drawbacks. Something along the lines of the Pre-made Group Finder we have in Retail serves the same function as spamming into trade chat, only without the extra spam of whatever political argument, gold sellers, or other nonsense the regularly happens in those channels.
Added to that, my main point of argument is that the communities that form on a single-server environment do so when players of like-mind actually play the game. The method in which those groups are formed(dungeons, raids, or otherwise) is largely irrelevant. When players come together and have fun and enjoy playing with each other, That is where the real value of interaction comes in. That is when friendships are formed. That is how server reputations are built.
But according to Kaver, The only time and place that can happen is after you already have a guild, and after you already have friends. Everyone else on the server can fuck right off, apparently.
