From what I can tell from the fan made LFG tool (which I will be phasing out of once the official LFG tool is up), not a lot of people farm CoF p1 anymore. If I want to farm CoF p1 for a particular reason, it’s normally selling the fine and masterwork equipment from the dungeon chests that spawn after either defeating bosses or doing certain timed events. But since the MF mechanic has been changed, it’s now more worthwhile to salvage the fine and masterwork items for the Essences of Luck (and I’d rather waste most of my time killing karkas to get the said fine ans masterwork items). Even so, prior to the dungeon reward revamp update, most people farmed CoF p1 as means of getting tokens to buy rares for salvaging them for ectos.
ANet is trying to encourage players to play multiple dungeon paths per day over farming a single path. It’s actually ANet’s stance to discourage farming (which ironically, there is a lot of level grinding in terms of leveling and crafting, which means farming is necessity).
From what I can tell, Citadel of Flame and Ascalon Catacombs are the most popular dungeon runs (one is for the said CoF p1 farm, and the other is for obtaining the PvT gear). I rarely see runs for higher level dungeons or CM (sans Ruined City of Arah, which is arguably the hardest dungeon).
Thanks for replies!
Briefly installed, tried out a few old dungeons
… but working on my chochobo license atm. I really hope the permanent dungeon content comes soon.
