Thats not how adults argue dude. You want to make a claim you prove it. you dont get to make a claim and then leave the work of proving it to your opponent/ That literally is how most idiotic discussions in this world begin.
If you make a claim, prove it, link things, say things, math things yourself.
Even if your opponent is wrong.
Also ad hominem plea(s) citing your own savage clears is both petty and pointless.
On subject, thinking about break points for skill speed and specific rotations is very much a form of proper optimization, and many classes do it. Note this segment from the balance:
"Q: Why is looping important?
A: In order to minimise personal ability cooldown drift and maintain perfect alignment with raid buffs on intervals of 60/120/180 seconds it is important that our rotation allows us to use our 2 least flexible abilities - Meikyo Shisui and Tsubame: Gaeshi - as soon as they are available. Since Tsubame is on a 60 second cooldown we need to target a specific GCD tier to achieve a clean GCD cycle that comes as close to 60 seconds in length as possible.
Refer to http://bit.ly/Compendium-Loop for in-depth explanation.
For comparative purposes we always assume Y/G/K Meikyo and G/K Bana.
Viable SkS tiers for looping:
2.13 ( 28 GCD Loop ) - 812 SkS - requires 1 filler GCD
2.06 ( 29 GCD Loop ) - 1,624 SkS - requires 2 filler GCDs
1.99 ( 30 GCD Loop ) - 2,437 SkS - requires 3 filler GCDs
1.92 ( 31 GCD Loop ) - 3,249 SkS - requires 4 filler GCDs
1.86 ( 32 GCD Loop ) - 3,960 SkS - requires 5 filler GCDs
(Taking human error and server network into account allows for the slightly faster tier, e.g. 2.05, to be as viable as 2.06. Applicable to all listed tiers)
Filler Options:
1a) double-Yuki Meikyo - equals 1 filler GCD
1b) non-Yuki Meikyo - equals 1 negative filler GCD
2) Yuki-Bana - equals 1 negative filler GCD
3) Yatenpi - equals 1 filler GCD
4) Yuki-kure - equals 2 filler GCDs
5) Gekko-/Kasha-kure - equals 3 filler GCDs"
Oh look i cited a source where comprehensive math was done.
Additionally SAM is absolutely by no means the only class that cares about SkS/SpS.
BLM massively so, MNK still loves SkS with for the most part only ever single weaving, and they have to also try to hit specific tiers to enable ceratin optimised rotations such as the double true rotation. Even DRG do a bit. The highest potential dps SCH build right now is even SpS focused.
BRD and NIN care about keeping it low in current iteration.
Being belligerent and providing one word answers with obtuse statements that are not backed up by any source or calculation at all literally helps no one.
