TopUse Q to keep farm reachable, and do not auto-walk to every passive canister; a lot of bad Mundo lanes come from turning a dropped canister into a free trade for the other top laner instead of letting it go and punishing the stomp later
W should be running for the burst that actually decides the trade and recast while you are still in contact, because Mundo feels much weaker when the spell burns on harmless poke and expires before the real damage lands
Good Mundo games often look like side waves becoming a tax on the enemy team, where recalls, dragon setups, and slow rotations keep costing them tower health because his wins are unusually tied to building damage and turret takedowns
Only when the pickup is cheaper than the punish. If the canister drops into the enemy's threat zone, near a stacked wave, or with jungle pressure in the area, let it go and keep your health. The mistake is treating every canister like guaranteed value when good opponents are waiting for that exact step. Look at who controls the space first: if they have to walk up awkwardly to crush it, you can answer with Q, trim the wave, or reset the trade after they commit. If they are happy to hit you for it, the canister already did its job by preventing the first CC.
