Why mark targets?

[SpecialKK]

Am I missing something here? Going through Roulette, I've encountered many DPS who become very frustrated when I don't mark targets. This is especially annoying when they don't use AoE when we pull 3 or more targets, and focus down one at a time (subsequently risking pulling enmity).

Damage over time abilities (e.g. Fracture, Touch of Death, Venomous Bite) yield superior DPS, so it's ideal to apply every available DoT to every enemy (unless you're using AoE), at least once at the start of each pull. Marking targets and using only single-target combos yields inferior damage.

Of course, as the pull progresses, re-applying the DoTs may not always be the best idea (since DoTs usually take between 9-18 seconds to achieve efficiency).

As a full 90 DRG, most mobs when single targeted die quickly on dungeons. Since my dots won't reach its full effect by focusing on single-target, its a waste to include them on my single-target rotation. What I do instead is do Impulse Drive -> Disembowel on my main target, but then drop Chaos Trust DOT on a 2nd target. I believe this is what you're referring to.

That said, isn't this more reason to use Marks than not? If you are pulling 3-4 mobs at once and your party is out-leveling the mobs, then you Mark the following:

Mark 1 - Single target
Mark 2 - DoTs
Mark 3 - Next target

By the time the DPS finishes 1, then #2 should be pretty much dead from the DoTs. DPS then finishes it up and drops the next set of DoT on the 4th mob, while proceeding to Single-target Mark #3.

The fact is, using marks can only help your group be more organized and takes away the guessing game from the DPS on which mob the tank is building hate first. There really is no reason not to use it.
