timeframe 33 seconds

Fracture is only 300 potency for WARs thanks to the extended duration (100 + 10 ticks of 20). For PLDs, it's a mere 220 (100 + 6 ticks of 20).

As such, there are 3 basic "rotations" to discuss:

RoH x 2 + Fracture (Fracture will be reapplied just before Fracture fades; because of how DoTs work in FFXIV, that's actually right when you want to refresh them):
(150 + 200 + 260) * 2 + 220 = 1440 pot over 7 GCDs = 205.7 pot/GCD
(70 + 60 + 60) * 2 + 80 = 460 TP over 7 GCDs = 65.7 TP/GCD - 50 TP/GCD regen = 15.7 TP/GCD net loss

RoH spam:
150 + 200 + 260 = 610 pot over 3 GCDs = 203.33 pot/GCD
70 + 60 + 60 = 190 pot over 3 GCDs = 63.3 pot/GCD - 50 TP/GCD regen = 13.3 TP/GCD net loss

Riot Blade spam + Fracture:
(150 + 230) * 3 + 220 = 1360 over 7 GCDs = 194.3 pot/GCD
(70 + 80) * 3 + 80 = 530 over 7 GCDs = 75.7 TP/GCD - 50 TP/GCD regen = 25.7 TP/GCD net loss

As such, you'll see that Riot Blade + Fracture is the worst possible rotation by a fair deal. Even if it is ideally the lowest threat you can do, it's going to bottom you out *way* faster because Riot Blade is so inefficient. Fracture is also way worse than you thought it was. I wouldn't even bother with it, honestly, since it's a mere 1.2% increase in damage dealt but a much larger increase in TP consumption (way more net loss and a 3.8% increase in consumption over time).

The lack of 2x enmity modifier while out of SwO should be more than enough to allow you to RoH spam with impunity (.8 * 2 = 1.6 compared to SwO's 1.0). About the only time you're at risk of pulling off of the MT is if you're using FoF and/or you get a crit with RoH (SwO with FoF = 1.3; SwO crit = 1.5; SwO + crit + FoF = 1.95) immediately after a neutral enmity condition (someone just provoked or you're starting with a fresh enmity table).

k, you got me there with 6 vs 10 ticks, but no1 said you needa pump in riot combo the entire fight. it was an example how you can use every gcd right from the beginning or after tankswaps, w/o fear to pull of aggro

You're not going to be served using it for any extended period of time. At best, I would use it 1-2 times at the start if you're really worried (which you really shouldn't because the MT should be leading with a Shield Lob/Tomahawk and be a GCD ahead of you for combos). For any tank swap, you're almost always better served by simply Stoneskinning your tank partner: it generates less enmity and is, honestly, more useful than the couple hundred damage you'd do in those few GCDs.

what I have resorted to doing is stoneskin --> riot combo --> riot combo --> stone skin. that is definitely not set in stone, but you still get decent damage in SO, and you have no chance of taking aggro. if you are in a fight that requires tank swapping do the same thing but if your good you can stance dance well enough that right after u provoke you hit the combed Halone
