Monk Macros with Proper Rotation!

[Bloody]

If Player A is doing 1000 DPS, and Player B is doing 800 DPS, Player B is doing 80% of Player A's DPS, right?

So at 2 minutes, aka 120 seconds, Player A's total damage should be 120000 damage. Player B will be at 96000 damage.
96000/120000 = 96/120 = 80%
So at 2 hours 15 minutes, aka 135 minutes or 8100 seconds, Player A's total damage should be 8,100,000 damage, and Player B should be at 6,480,000 total damage.
6480000/8100000 = 648/810 = 80%

The total damage numbers will increase over time. But as long as the two DPS numbers remain constant, the percentage difference between the total damage numbers will remain constant. Where you will see variances is due to cooldown use. Neither Player A nor Player B will use their cooldown exactly the same way, especially when comparing various methods for doing things! And so their constant 1000 DPS and 800 DPS, or whatever the actual DPS comes out to be for any given period, will not be the same for all such given periods.

This is true, assuming other factors aren't involved. Phase shifts and other mechanics that ruin a combo will break the macros, and result in a DPS plummet during such mechanics.

But with macros the gap between the number gcds used versus a non macros rotation increases over time.. there for increasing the dps gap

While that may seem true, the percentage values actually stay the same (barring aforementioned mechanical interference). As Roth pointed out, raw values will increase, but percentages will remain constant, assuming no interference. The instant mechanics cause rotation pauses, this difference grows massively (as already mentioned by others).

Macros are good for:
Announcing key skills like: Raise, Mantra, Berserk, Provoke, Blunt Arrow, HG/HG/LD, etc.
Crafting and Gathering
Making loot lists (back before lootmaster or even now to show newcomers who has reserved what)
Making miscellaneous chat/emote/action combos (which I expect to see in that APR performance on the 30th to help with lengthy lines in the script)

Macros are NOT good for:
Combat rotations

Macros are in the game for a lot of reasons, but just like existing gear, this rule applies: Its existence doesn't guarantee its usefulness. Remember that.
