Well I did the math, if youre "Taking time" to aim then youre doing even less damage and shooting even less shots at Atheon. I shoot P&T extremely fast and in the weak spot and I dont miss (Because its extremely easy to hit) and we kill Atheon in 2-3 teleports. He dies before I ever have to Synthesis, and I never use my sniper on anything else because my Epilogue/Vision and Heavy weapons are much better at killing everything else.
