Yes there is, but it involves thinking outside the box and unfortunately drastic changes in code and Link Shells....

For example:

1.) Imagine a +100 myth tomes weekly reward for being on a team with a person who has NOT completed a trial that completes it. Instead of charging for Titan Runs you'd have groups PAYING newbies for Titan runs....

2.) Imagine a game wide (instead of server wide) link shell so when you find awesome people in PF you can team with them again....

3.) Imagine a more drastic punishment when you're vote kicked from a group more than 5 times in a week... (ideally for things you have not completed before to avoid blocking story progress)

4.) Imagine if the game encouraged team work from level 1 instead of being a solo game with an occasional PF dungeon until you reach level 50 and you're suddenly expected to have a social network...

5.) Imagine if there was a punishment for quitting CT after getting some loot.
