Not sure if this is normal or not since this is our guild's first time attempting raid boss chapter 13. However, we're noticing that it doesn't drop loot at each break point like the bosses on chap 7-12. Not sure if it's (1) bad luck on our part, (2) that's how it's been designed or (3) this is a bug that needs to be reported.

I'm wondering if I could get some feedback from other people in guilds that have cleared the chapter multiple times.
