I have had an increasingly difficult time finding groups to do the 4 man dungeons on my journey from 1 to 50.
1. As I completed each zone, the closer I would be to leveling past the group finders level range for the next zone. Knowing this, I started looking for dungeon groups that end at level 43 before I even entered The Rift. I knew the dungeon would be at the other end of the zone and I would level past 43 before I found the dungeon. I am not alone with this problem as there are others like myself that like to finish all the content in a zone before moving on to the next.
2. When I was within the correct level range to use group finder immediately it would find another DPS and the 2 of us would sit in a group for 2 hours until a tank or healer was found and then the last spot would be filled an hour later. It doesn't speak well for population balance in the game. Seems most of us are playing DPS characters.
3. A player in another faction was struggling to get a group formed. I offered to go along . Turns out we couldn't group together to do a dungeon that wasn't in our factions anyway. Are we breaking some sort of protocol if we quest to save our enemies from some great evil? Guess what? We do it for 2/3rds of the dungeons anyway.
Have the group finder find people of higher levels and from any factions. This should allow us to form groups faster. Also make tanks want to tank and healers to want to heal so that we can have more of them. This is an MMO and I want to play with other people. I don't want to run around solo questing all the time. That's what Skyrim is for.
