Often I realise people don’t even read their skills each step is 1 sec, that mean 2gcd + 2 secs for standard steps: 2:45 sec multiply 2 + 2 sec for steps so it’s less than 3 gcds. You certainly want to use Standard steps as often as possible! Cascade + Fountain + RC/FF is 750/800 pot vs 1k of Standard steps
Technical steps is 2 gccs to dance + 4 sec for steps it’s less than 4 gcd in total for 1.5k pot.
Opener wise at lvl 80 my guess ( and it’s just a guess) you will use Standard step 15 sec prepull (just for the buff) then Techincal steps around 10 sec prepull and land your 1.5k skill on sec 0 to spread your 20sec buff to the team. On the 5 gcd you will see probably TA go up and BOOM:FLOURISH!! Then Standard steps again at sec 20ish into the fight ^^

Hope that help
