"Deus ex Machina" Machinist Burst Rotation

[Gamer3427]

That first Lead Shot is mostly just filler to be doing some damage while you're getting the other skills set up. Doing another hot shot before hand would eat away at one of the ammos you'd otherwise have in your Wildfire rotation. As for the other buffs, having them up for longer on the skills in the Wildfire is more beneficial than having them up for the skills pre-Wildfire......

EDIT: To put it a little better, expending an ammo to have Hot Shot up for that first Lead Shot and Split Shot isn't quite as beneficial as saving that ammo and having it in the Wildfire rotation where it's essentially a fully buffed 25 potency, (20 base potency + 25% of damage redone when Wildfire goes off). Particularly as Lead Shot will only be up for three or four ticks at most before you replace it with a fully buffed version......

The already-existing opener already uses ammo for 7 out of the 7 weaponskills (thats counted for wildfire anyway) without risk of desyncing your reload cooldowns from other skills or the fight (A3s for example), and has all cooldown buffs (and hot shot) for wildfire and lead shot in the beginning. You're losing out on buffs for an attack that does 490 potency (your strongest potency in a single GCD as a mch) over 30 seconds.

Here's my opener:
Rook out > Gauss barrel > Hot Shot > Lead Shot > Reload > Rapidfire > Blood 4 Blood> Raging Strikes > Hawks Eye > Hypercharge > Wildfire > Split Shot > Slug Shot > Split Shot > Reassemble > Clean Shot> Blank > Head Graze > Slug Shot > Richochet > Gauss Round > Quick Reload > Split Shot > Slug shot > (wildfire usually detonates here)
