It really depends on what style of player you want to be or are.
The new system takes away the social part, I use to run about 11-15 dungeons a day when I was on EU and barely anyone spoke, they had all done these dungeons so many times and just power through...
The most typing was "Wait, Mana" "Telephone brb"
But if it's quick badges and gear you want then it is perfect for those players.
Sometimes still people would create their own groups and do dungeons, just to have that social feeling.
But if its a quick dungeon you want, its perfect.
