Ok, you talk about the +5 kenki every 9+ GCDs, I get it. Sorry I wasnt considering that as a positional requirement. It is a miniscule DPS boost if you move around once every 9 GCDs, that is correct. What I meant was stuff like NIN TA not even doing its primary function, or MNKs massive potency losses on every GCD if you are not in the correct spot.

But yes, technically Samurai would have to do a little sidestep every 20 seconds. Assuming a GCD of 2.4 roughly, uninterrupted, doing that sidestep nets you the 25 extra kenki every 132 seconds if my math is correct (including Iaijutsu), or lets say between 120 and 140 seconds. (you will always be in a position to hit ONE of your positionals, thats why I only calculate the other that would require you to move). Titania EX has about 7 minutes actual fight time, minus every second you need to move. So you build an entire 3, in a REALLY slow DPS group hitting the enrage maybe a 4th Shinten over the entire fight, assuming you never overflow, mismanage or step wrong, that means a total of 960 potency. Also called "less than Shoha nets you in that fight", a skill widely panned as useless.

I dont really see that as a positional playstyle. sorry. Especially since Kenki generation is also not gatekeeping any opener or general rotation issues of the more important skills.

I would presume that having the SAM stay in one position is actually more beneficial due to clarity of movement, positions and raid placement over 3 more Shintens per clear.
