Nino,
You can find my suggestions concerning LFG here:
http://www.fohguild.org/forums/666173-post103.html
Part of the Gameplay suggestions thread as Forge pointed out. My personal favorite is the Group Proposals system (the last one)
Here, reposted to make it easier:
• Healers should be able to summon people within the same continent. If you want to avoid this being used for fast travel, punt the player back to the point he was summoned from after leaving the group. Give a 5 minutes grace period after relog if the person goes link death or crashes, but worst case scenario he gets punted and you just have to summon him again.
• Give summon spells to offensive casters, so they can summon healers.
• A Matchmaking system should be put into place that would dynamically suggest group setups from among the LFG crowd. All people should have to do is press the LFG button.
• People should be able to share quests they have already completed.
• All LFG options should be available from within vgplayers.com via a web interface. You should not even have to log on to the game to look for groups. When the group is formed, pressing one button should launch the game with the appropriate character. And no Smedley, you should'nt charge money for that option
• You should be able to tick off certain quests as being LFG specifically for those; the system would try to match together people doing the same quests.
• You should be able to select specific dungeons or chunks you are LFG for; the system will match you with people interested in the same.
• You should be able to create "Group proposals". You create a textual description of what the group would be about "I'm looking to start a group that would take on the first tier of quests for the dungeon of DwarvenName's Place." Then you would assign specific requirements that the group needs before starting (say, 1 tank, 1 healer, +2 more random classes). People can see you group proposals and subscribe to them; as soon as the system sees that the requirements are filled, the group is formed.
