Yeah, there was multiple openers. I remember, at every wipe, having to reload, put on barrel, place turret... Hated those times. I don't remember the exact opener but you had to start with 3 ammos.
Hypercharge pre-pull, Hotshot+GR, Split shot, Slug shot+reload (Clean shot prepared), then Flamethrower. Break FT at OH with Split shot, WF+Reassemble then classic 3-2-3 with 2 heatblast and Overload.
Wildfire as the core wasn't a bad thing, not in HW. But in SB it was always the same wildfire, you had nothing to do between each wildfire except replacing turret and care about the heat gauge.
Gameplay was Wildfire -> play with proc -> Wildfire -> play with proc -> loop. With of course caring about the auto-turret.
