•Walk first, flag second: on many ganks Jarvan should use body position, W, and red buff to make the target show their escape line, then spend EQ as the receipt, with R first into EQ as a real punish when they still have a reactive dash or flash
•Cataclysm is a door, not just a cage: use R to close helpers out of the half-fight your team is already winning or to pin the diver who reached your backline first, and break the wall if it starts trapping your own team instead
•Spend Martial Cadence on new bodies: Jarvan’s cleaner fights are often the ones where he stamps one target, switches to another, and lets his team finish the arranged play, which fits the recent data showing he wins more cleanly from ally-layered setup than from forcing random 1v1 river tests
