Lanes that still have a tower
Pull, block, and trade when the creep wave allows it. A 1v3 death at minute four is a map. Wards before hero quests.
Open this resource when a new patch moves regen or support items.
Objectives over pickoffs
Towers, Roshan, and high ground win. A chase into fog for a courier is how you donate buyback. Save gold if a fight is coming. Spend it if the next objective is free.
Smoke for a reason. A smoke with no ward vision is a group walk into a counter.
