Hey guys,
Did this post for my guild but thought I'd pass it along here too.
Here's a damage breakdown for Garalon's unavoidable attacks:
So, as y'all can see, no matter how many stacks we take, it's roughly the same damage per minute. At 10 stacks you take one 150k hit every 20 seconds, with pheromones only stacking from 20k-22k-24k-...-40k, whereas with a 4 person rotation stacks go up to 50k per 2 second ticks, but with the 150k crush every 30 seconds. I was honestly surprised though to see that the total damage taken per minute only varies by +- 3%.
Also, I did the differential. While I didn't get a screenshot of it, minimum damage taken is at 13 stacks, with a 4.6 person rotation...so you'll need a gnome for that last 6/10ths of a person. :P
