taking these out a bit further,
suggested on top, alternate underneath:
(EDIT: there is a mistake in these sequences as well. additionally, this sequence describes only the situation where you have 4 HoPo, J is off CD, CS is off CD in 1 global, and Exo is off CD in 2 globals. not sure why i just went with Loryath's list instead of the base case, but i did. please see post below).
J TV5 CS Exo J TV5 CS TV3 J CS x x CS Exo J TV5 CS TV3 J CS
TV4 CS Exo J CS TV5 x CS J TV4 CS x Exo CS J TV5 CS TV3 J CS
compare these two. both cases have 2 open GCDs about to happen. both cases leave the cd on J and CS at the same place. both cases have the same HoPo (2). case 2 has exo coming off CD 1 GCD earlier. both cases have 2 open globals. both cases use 5 TV, 2 exo. case 1 has an extra J, case 2 has an extra CS. we have just turned a J into a CS, with the additional benefit of a slightly sooner next exo, and since exo is 1 spot sooner the entire time, we are allowing for more AoW procs as well.
just to show that i'm not ending the rotation at a convenient place for my theory, here's what comes next.
x x CS Exo J TV5 CS x J CS TV3
x x Exo CS J TV5 CS x J CS TV3
everything is identical here, other than the early exo from the proposed rotation. also, note that the proposed rotation could in fact simply revert to the accepted rotation at that point, as exo and CS come off cd at the same time. this isolates the lists above. doing the proposed sequence above turns a J into a CS, with zero negative impact on the rest of the rotation.
(EDIT: again, there is a mistake in the sequences. my apologies, please see post below.)
obviously, this ignores AoW procs (which favor the proposed rotation), it ignores avenging wrath and sub-20% (which also favor the proposed rotation), and it ignores lv90 talents (which again favor the proposed rotation).
the reason HoW and lv90 talents benefit the proposed rotation is that they consume GCDs. the real thing we're worrying about here is preemptively stopping ourselves from delaying a good HoPo generator (aka not judgment) in favor of TV5. this is a situation which does in fact occur, even in the normal rotation (non-wings, non-execute phase). the more abilities we add to the rotation, the more likely it will be that we become "handcuffed" with TV5 and CS/Exo/HoW available at the same time. delaying J can loosen this, and when you get proccy you can sometimes go for quite a while without needing J to fill the globals.
my mistake was not putting the first Exo ahead of CS in the accepted rotation. both rotations get the same benefit from Exo and AoW, there is no edge for the proposed rotation in this situation, as far as Exo/AoW goes (actually i suspect there is still a slight edge due to the 'handcuffing' effect, but it's not something that's easily demonstrable with a simple spell sequence).
the proposed rotation still turns a J into a CS, however. both rotations still end up at the same place (regarding spell CDs and HoPo available).
accepted rotation on top, proposed rotation underneath:
J TV5 Exo CS J TV5 CS TV3 J CS x x Exo CS J TV5 CS TV3 J CS x x
TV4 CS Exo J CS TV5 x CS J TV4 CS x Exo CS J TV5 CS TV3 J CS x x
this sequence can be truncated after 11 GCDs, the rest is just for show.
