FATE parties used to be so much more common though they haven't been in a long time. The only areas that still have them barely are Coerthas and maybe Costa Del sol. Because before you would FATE in Aleport > Quarrymill > Costa > Coerthas > Bluefog or just stayed at Coerthas till 50. You can FATE while waiting on DF but you won't be in party then so you'll have bunch of people running around without much communication to which FATE or someone to heal tanks that are MTing the FATE bosses.
