Non Standard seems to exist again, thanks of the change (not sure, if it allready existed earlier).

Standard should be around:
Casting both ice spells to fill the symbols. Cast fire3 to switch to fire. Cast fire4 until flare Star is ready. In between can you use paradox and fire 3 proc (or keep the proc for later). Onces, you mp is 0, are you using B1 to switch to ice and fills everything up again and restart it.

But, i have read, that the Real rotation, people are using is:
Start with fire3. Use fire4 until mp is 0. Use mana font. Use f4 again. Now, can you use flarstar. Than, can you cast F4 again, until the mp is 0 and you cast flar Star again. This rotation sacrifice Paradox, to use FS 2 times.
Now, are you using transmog to go to ice, for a bit more dmg. Maybe use a Quick spell skill to cast B1 faster. Fills the ice stuff and use paradox. Than, switch with transmog again to fire. Use paradox to get fire starter and use than f3 to start the fire phase.

Its so out of the normal line, that it seems for me to fit the term "non-standard".

Aoe is even more simple. Use 2 times flare and than flare Star. Use transmog to switch to ice. Use freeze (or what the aoe Version was), to get the 3 shards. Use some filler, until you can use transmog again. Switch back to fire and cast again 2 times flare.
This variation is very fast and make with it good dmg. From what i have read.

And the base for the ST rotation seems to be, that whe dont have a timer anymore, that force us to use paradox earlier.
