Double True strike isn't a thing at the moment, so this is wrong (based off of info from Balance Discord).
DK > Twin > Demo > BS > True > Snap > DK > Twin > Snap > BS > True > Demo
Same length of attack string, that is 3 positional movements.
Every Perfect Balance, assuming 100% uptime, will swap DK and BS in the rotation;
BS > Twin > Demo > DK > True > Snap > BS > Twin > Snap > DK > True > Demo
so if it started with BS instead of DK, then you have 8 movements, bearing in mind this is over 12 GCDs.
At this point, we cannot say how Blitz will interact with the rotation and until we get more info, it will be impossible to tell. Should they have removed positionals from Raptor Form? In my opinion, no, but until I get my hands on EW Monk, I am not going to comment on something I do not know.
As for positionals being part of a Monk's identity, probably not, however it has always been a key part of how the job plays in the same way that one of the key features of Black Mage is finding that spot to stand still on.
Monk used to be a quick attacking crit machine between guaranteed crit on Bootshine and Internal release increasing critical rate. It was also the highest DPS which was balanced by GL stacks and doing positionals. You want the high damage, you have to work for it.
Over the years it has lost Internal Release and so it wasn't as much of a crit monster as it was before, Lost GL management and is now no longer the highest DPS. All Monk has from it's inception from ARR is it's positionals. As Monk players, we are literally holding onto one of the last things that made the job unique and stand out from the rest and, to top it off, Monk hasn't gained anything else unique to try and offset what was lost. Want positionals lessened? Give me a reason to want to lose positionals, don't just take them away for the sake of taking them away.
