Why mark targets?

[YuriRamona]

It really doesnt take much effort on your part to mark (Macro if you have to). Marking also helps BLM/WHM know which targets they should sleep, as well as tell the party kill priority. For example, in Haukke you have the Maidservant. Some dps may not know that they take priority over every single monster in that dungeon, so def mark that.

Sleeping targets is pretty much the worst thing possible for damage, and is to be avoided. Party compositions are not made to always include a WHM or BLM with sleep, and the dungeons simply aren't tuned to require it.

Marking, even a single mark over your current target, helps keep the group focused and will increase survivability due to the decrease in damage taken as individual targets fall.

It may be worse outgoing dps, but it is better for incoming dps as dead targets can't deal damage.

Again, in my first post, I outlined that the exception is if the healer or tank are undergeared or inexperienced. If that's the case, any concern about maximizing damage goes out the window and we are in survival mode. Marking targets and CC are essential, in that instance.

You've got it backwards. If a Tank focuses on 1 target and dps focuses on that target while not severely overgearing the tank (dps has Zenith, tank has 55 darklight) dps will rarely pull enmity off a tank. AoE Ramapage are more likely to pull something off the tank and onto the dps doing the rampage.

Losing enmity is a major concern because there will often times be one DPS who knows what they are doing (spreading damage, using AoE, upkeeping DoTs) and another who insists on focusing on one enemy and using single-target abilities. I don't think I should be at fault for trying to ask DPS to maximize their DPS and spread their attacks, just because everyone is habituated to focusing down one enemy at a time and marking targets. The tank shouldn't be the one bending over backwards to adapt to DPS that don't want to fit with the tank's style.
