A Dungeon Finder should be a tool to find and compare players for the dungeon I want to do. Nothing more. Spamming LFG in public channels is not fun. The DF eliminates that. I don't want it to hook me up with people on other servers/realms. The anonymity gives players the power to be rude, leave groups, fake disconnects etc. with no social punishment. If a player behaves badly you can socially correct them in your own social circle. For example: Tell your guild mates to not group up with player X because he is rude. To counter the problem on finding a group on low population servers is to make it a single server only game (like EVE) only split by game rules (PvP, PvE, RP or any combination). The technology is there. The reason they split up servers anyway was to control the strain on the servers more easily. That isn't needed anymore. Instant porting to a dungeon makes the world feel small. But traveling to a dungeon entrance after you did that one 30 times already is not fun either. So I think you should earn instant porting if you are a veteran player. Make instant porting a reward for doing it a number of times for example. And make this work with the DF as well, so that players with the port shouldn't have to wait for players who haven't got it yet.
