My only issue is that I feel that the drop rate of 100s unit is way too small. Been doing Dynamis every night for the past week and a half, and we killed more NMs that I can even remember, and so far only 1 100 has dropped, and that's a 100 byne bills. I don't even think it's 5%, but then again, I'm probably doing something wrong. When it comes to Beaucedine and Xarcabard, I know a lot of the placeholders, and utilize it constantly while pulling and killing regular mobs. Killed several NMs, and just not a damn 100.
The drop rate off regular mobs is fine if they are staggered. In the single units, I've seen 150~250 with 5~7 people.
