Unlike Gwydion, we didn't get many BT necks, so the necklace percentage may be slightly off. Still, it's quite obvious the drop rate for BT necks was very low, based on feedback from other servers.
How low? Here's how it was in Morrigan:
I think it's safe to say that Necklaces had about 10% drop rate, Charms had 30% and Rings 60%. I think it wouldn't have been so bad if the ratios were 20-30-50. It was extremely frustrating killing over 400 trees and get ring after ring, charm after charm.... if you don't believe me, just look at these recent posts: here and here. I wasn't the only one.
Out of all the necklaces we got, here's our drop rate:
Yep, 3% Bloodthorn. So to get a Bloodthorn Neck, we need to hit the jackpot and hit that 0.33% drop rate. That's a third of a 1%. Lousy odds ain't it?
If Gwydion got about 8 BT necks, and Necks typically drop 10% of the time, I'm guessing they had around 50-60 necks total, giving them about 1.3-1.6% drop rate. That's over 5 times drop rate that we got. Lucky server.
Here are the stats for rings/charms (probably uninteresting since all servers got flooded with them)
To those saying drops are skewed towards casters, here are the drops by type:
It seems to me that Stonebark, Spiritseed, Shrivewood and Ironroot have similar drop rates - about 15%.
So that's about 45% caster drops, 15% tank, and 40% DPS.
As for the DPS, they are either weighted as 10% each for Bloodthorn, Bladeleaf, Frostroot or Stormleaf, but it feels that Bloodthorn has always been rarer, so perhaps it's a 7-11-11-11 split.
