Here's a quick timeline of a stretch:
3:05:33 - 31 debuffs applied. 9 magic, 7 poison, 9 disease, 6 curse.
3:05:43 - 27 debuffs applied. 3 magic, 8 poison, 9 disease, 7 curse.
3:05:53 - At this point some debuffs are already de-syncing with a timer, and there is so overlapping, but a rough estime: 30 debuffs applied. 5 magic, 8 poison, 8 disease, 9 curse.
3:06:04 - 30 debuffs applied. 11 magic, 5 poison, 6 disease, 8 curse.
3:06:14 - 32 debuffs applied. 12 magic, 5 poison, 8 disease, 7 curse.
3:06:24 - 33 debuffs applied. 13 magic, 6 poison, 8 disease, 6 disease.
3:06:35 - By the time this wave hits there's still ~9 magic up, and 35 people have debuffs on them. It's all downhill from here.
Is this for real? Am I missing something here? 183 debuffs in 1 min, not counting the ones which are applied off-sync with the 10 second interval.
Edit:
I have no clue about the Bronze. All I know is that after ~1 minute the entire raid was blanketed in Bronze and was stunned for what I believe was 25-35% of the time. With limited sands you just have to roll with it, and if it's a random 10-12 players per 10 seconds (mind you I also think the 10 second interval is 33% too fast) it's getting sticky rather fast.
