Isnt it like better to make 2 3rd degree burners keep track of boss debuffs and once you stack 20 /should be quick on how fast this thing procs stuff, i actually used storm reaver pendant so i can tell that vorpals happen super fast in a haste boost, then when you stack 20 do a hotswap to your regular boss beaters, no idea, whatever you prefer.
That way you negate need for fire toee, and it literally takes couple seconds to stack 20 and you are back to full tard dps mode with lets say a acid temple + a first degreer dragon edge whatever 3rd tier.
At least thats how i usually play melles, yes its a hotswap, but it raises your dps
