You use far too many commas and your grammar is terrible. Format your posts more appropriately in the future.
From what id expect, we need enough haste, to buff the talented SF to leave our hands, before the Incin/SB hits the target. We sould still need to start off the rotation with SB,SB,SF tho
What i expect people are seeing on test, is due to the lag its being made possible, but with reduced lag on live, i dont think it will possible to replicate, unless you can get it down to under 1 second with haste rating, either way, we should gain the buff when the spell leaves our hands as its buffing us, were not debuffing the boss. Should proc from "Besalyn casts Incinerate" and not from "Incinerate hits <insert boss>" ofcourse that change could lead to fake casting incinerate to spam SF but i wouldnt see that as a dps increase.
