I think this is a good idea IF implemented in such fashion
Allowing the player to manually sync level, and only forcing level sync in these situations,
during lower level FATE's, and in dungeon party's comprised of lower level player, and then outside of these circumstances ALLOWING players to CHOOSE to turn level sync on or off.
i think this is a great method for keeping all end-game content "current" i.e. raids.
has any info been announced regarding if level sync will be forced outside of outlined circumstances listed above? i would hate that, its what ruined GW2 for me.
