Before stamina I loved quad engi spires with three buff hammers. Pilot brings span mall buff kero and upstairs engi has hydro. Start engagements with all buffed guns and components, and a buffed hull with extra span mall makes a big difference. Weaknesses were close range where all three tools become useful, and against heavy balloon popping. It's still great for sniping, but stamina is far too important even to sacrifice the buffed gun and hull power
