you should be switching between demolish and snap punch.
Put up demolish first for the dot. then use snap punch the next time since demloish is already running, and then by the time you get your next couerl form demolish will need to be refreshed as its about to fall off.
You snap punch when demolish is already up, or if you know the thing you're attacking is going to die or something soon and know that demolish wont have enough ramp time.

Because it's not a training dummy and your rotations gets fragmented in a fight.

the boss is not nice enough to say "oh you finish your rotation, i'll do my thing"

The last phase of a boss battle, there is a high amounts of fragmentation, which breaks down your internal clock

it is much simpler to dk-twin-snap all the time, and then throw in a demolish on a whim then keeping demolish up.

Shouldn't you be able to do 100% beginning, 70% mid and 60% end. Using your numbers anyway. If you can't produce in a clutch there's no reason to not to produce when you can.
Valsh was just saying that always is a strong word.
The combat is enough that you can adapt depending on the situation, so yea can follow an easier "rotation" if your buffs are going to fall off and boss uptime is low.

If we just called it a a priority system, no one would even think twice about this. But we have to do it in cycles so everyone's hung up on considering it a rotation.

Well yes theoretically you should be doing 100% at the beginning, but there is such a thing as muscle training or worse, macros, and the more you try to train a complicated system, the more it'll fail you when goes irregular.

But yes, a priority system is best described. Heck drgs rotations of death, the first thing they must learn is to straighten out their priorities. NO boss is ever going to let you do your rotation of 20+ skills.

Reason I said, snap before demolish.

On the learning and journeyman stage of the battle, just dk-twin-snap will do woooonders for your battle. Spam all the IR you want, the bfb you want, the dodging you want.
