The LFG system in WoW made the game and world soo much smaller. With people all day queing up in major cities such as Stormwind and Orgrimmar. From that moment, pvp around summoning stones and instance entrance became unknown to today's New wow players. I can see the LFG system working, but if that happens, the LFG system needs to make the group travel to the instance on their own, not by the LFG teleport. Plus it has to be on your own server only.. not other servers included.
