Honestly now only reason is for the Wyrm Ash if you cap out on gear. No reason at all to do more than the 80 points daily since Oseem augment stones no longer drop from them.
Just to comment on this, that was a real stupid/*** move. They should've left drops on the dragons. (including stones)
Like, ONLY random drops from a mob, suck, you could go 1000 times and never get sanctity necklace
Or, you can now go for 2 days and get sanctity necklace 100% BUT, both is the best. This is always what I advocate for. You can keep trying to get the drop, and if you don't get it by the time you earn the points, you can buy it with points. And if you DO get it, the points go toward the next goal.
I wonder how the next DI campaign will go? Will they stop doing it because dragons no longer drop items?
And... I would really like them to add lesser warder drops on Zurim, that would be very nice.
