Turn 8: How do you trigger the towers?

[pacifist0rz]

I have a question about the T8 and the towers to which I hope someone would know the answer to. My group is currently working on the last phase of the fight and while we don't have issues with any other mechanics and feel like our tower rotation is working for us, there's one thing that occasionally wipes us and we don't understand how it works.

Sometimes when Allagan Field and Defense Reaction are supposed to explode at the same time, DR goes off a couple of seconds faster increasing AF damage significantly and basically one-shotting almost everyone in the group. The thing is, sometimes they blow up the exact same time and everything goes perfectly, then sometimes there's a difference of a couple of seconds and we wipe. I'd like to understand why this happens. I suspect it has something to do with either when we move to phase or when people activate their towers.

Our tower order is following:
1st set: Mines (2), DR2 (1), DR1 (0)
2nd set: DN (2), Mines (1), DR1 (0)

The random AF+DR happen during the first defense explosion in first set and the only defense explosion in 2nd set.

With the tower assignment that you posted:

For set6, you will have DR1 going off when the 3rd AF is at ~20 seconds. This is ok (it is how my group does it), and you just need to make sure that the AF target has stoneskin and Aldo. Alternately, you can try a different tower assignment that avoids this problem (such as the one posted by the OP).

For set7, DR1 should go off right after AF5 and before AF6 is cast (it is also how my group does it). Once we had it go off early, and we were scratching our heads like you. However, upon inspection of the combat log, we discovered that one of our mine sweepers got knocked into the AoE tower by accident, thus setting it off. Maybe the same thing happened for your guys?
