This is what im discussing:
I think sunny's proposed coerl quad opener(I filled in blanks im sure he may come up with something different)
Snap -> PB -> snap-> demo -> (b4b)snap ->(xpot)DK-->(IR) tws--> elixir field--> ToD --> chakra --> Boot--> Howling--> True --> Steel --> Demo
189 -> 207.9 --> 311.85(demo clipped) -> 270.27 (979.02)-> 225.225 --> 236.48625 --> 408. 783375-->450.074625 -->613.1750625--> 278.7159375--> 315.8780625 --> 353.0401875--> 278.7159375 --> 592.5294375 = 4731.643875
Hakmatic theorized rotation with 2.0 opener + fracture:
PB- > demo--snap-->snap-> b4b DK -->(xpot) tws-- >(ir) ToD--> Elixir field --> Boot--> Chakra-->True-->Howling --> Demo--> Steel --> Fracture
283.5(Demo clipped) -> 207.9 --> 226.8 -> 225.225(943.425) --> 236.48625--> 450.074625--> 408.783375 --> 278.7159375 --> 613.1750625 --> 353.0401875 --> 315.8780625--> 592.5294375-->278.7159375--> 382.370625 = 4853.1945
3.0 standard:
Demo--> PB-->snap-->b4bsnap-->(xpot) DK-->(IR) Tws-->Steel->Snap-->Howling --> ToD -> Elixir --> Boot--> chakra--> True--> Demo
367.5--> 207.9 --> 249.48-->225.225(1049.205) --> 236.48625 -->278.7159375 -->334.459125-->315.8780625-->450.074625-->408.783375 -->278.7159375-->613.1750625--> 353.0401875 --> 592.5294375 = 4911.603
This is the first 10 gcds only. As each rotation goes on, there could be a difference in which is better due to when buffs timers are up again and which abilities they hit, but no fight is in a vaccum of time, and thus there are breaks in fights and the fight eventually ends and where it ends in your GCD row plays a small role too, but averages out over extended amounts of fights.
Anyways as you can see, the one that starts off with going 1 gcd before PB was stronger than going PB using hakmatic's rotation. Thats all I was hinting at I even put the first 4 in parentheses that I was talking about to show the potency difference and obviously the final result. He was asking about a buff Snap vs a buff Fracture.
I have yet to see how Ossom's rotation pans out, but he has 13 gcds in that rotation, so I would need to extend the other 3 examples by 3 more gcds. I'm just waiting to see if he is going to add anything to it as I know he wanted to get his xpot in for demo iirc.
