Well Ihave to say the reason you got souless people is due to the people playing the game not the dungeon finder. Rift's DF is by far the best system out there never had a problem with cross server groups and the people were alot of fun. FIX DF
1. Cross server, Some of the servers just dont have enough people lfg all the time.
2. Ready check if everybody is not ready dont frigging pull them into the dungeon and mercs cant click the ready icon so dont include them in the group makeup. The ready check needs to be implementd to show up right before zone that way if sombody is not ready it replaces them insted of zoneing people in with a incomplete group.
3. Make sure you have the correct roles, Tank, healer, Utility, dps, other, other. If you dont have the basics dont throw people into a frigging dungeon. If the dungeon has mobs that will mez the healer then make one of the requirments 2 healers. But please stop throwing random classes into a dungeon and expect us to be happy about it.
4. Stat Checks, You have to have x hp/mit/cc to enter in with a PUG DF. IF your running sf pq gear they should not zone you into drunder or the rime instances thats asking for them to get one shotted which will ruin the experience for everybody.
5. Zone lock out timers. If it random it should ignore the lockout timers. Yes you might get a random dungeon 3 times in a row but its better then having your group zone in and then you cant get in because of a lock out timer. Lock out timers are a punshimnet against the DF change it.
6. On completion the exit should zone you back to where the DF pulled you from not right outside the dungeon. People might have been doing pq's hunting shinies, banking what ever. Put them back where you found them!
7. Incentive items. ok really glass gear nobdoy is going to take this as a upgrade cause they cant repair it. make it real gear or a random zone drop. Every one of these supposed incentive gear drops I have gotten I have destroyed. I cant even mute it. or better yet offer extra shards. at least then we can save up for gear or items that we really want. Glass gear is a bad bad idea.
8. 15 min lock out timer if you leave or are not ready. Again another punshiment against the DF if sombody gets up to do somthing and they miss it there should be no punshiment. Alot of people also will not zone out and leave if the groups are defined correctly before you go into the dungon.
Alot of aother games are making this work and I know sony has a talented programming team. Stop rushing stuff out the door before you check everything and actually make sure it works. You are really just making people angry.
