Guild Wars 2

I recently went to Curse Shore to farm karma by doing the event cycle. But there seems to be no one participating. Has it been nerfed in any way or is there a new method of farming for karma. My objective right now is to obtain obsidian shards so I would appreciate help.

I believe most people do either of the champ runs (frostgorge and queensdale) or the toxic tower events in kessex hills. Karma is pretty hard to come by nowadays, but i make a nice chunk doing low level fractal runs with a high personal reward level. i think i get about 8k karma per run.

The best karma farm is still WvW, because it never gets hit by diminishing returns.
