If your unseen E or R already applied passive fear, Q is now a fast damage button, not a second fear; press it early, then use the Fiddle brush-reset trick by breaking vision and re-entering to threaten another passive fear on a different target
Bot lane is often one bush or one wall for Fiddlesticks: E does the lane work, face-up W gets you punished, and when they own the lane brushes you should shift the scarecrow to river edge, tri-brush, or dragon-side over-wall entries instead of forcing visible trades
Treat vision like your real mana bar, because recent data shows support Fiddlesticks gets much more from one hidden-entry kill or prepared pick setup than from matching generic early roams on open vision
Start treating the lane as over-wall Fiddlesticks instead of lane-brush Fiddlesticks. Stop fishing with face-up W, keep E for checks, chips, and brush denial, and make your next threat come from river lip, tri-brush edge, or the dragon-side wall after a reset. In the 2v2, stand where breaking vision for even a second is possible, because that is what turns your next spell back into a real fear threat. If the enemy support is walking into you openly, Q and silence for peel first and let them overstep; if they are respecting lane, use that time to move the scarecrow to the next corner they have stopped checking.
