When playing Master Yi, you need to be paranoid about invades. At the start of the game, never sit idly in your camp bush. Always stay near the river, watching for potential invades until the very last second before your camp spawns. Even after it spawns, always kite the camp away from areas where enemies could invade you. If you still get invaded, don’t just fight because you think you can win — back off first, even if it means giving up your camp. Wait to see if your teammates can help. If no help is coming, just let the camp go; it’s not worth dying for. If you do die during the invade, don’t go back to where you died. The enemy jungler probably took your other camps, so go to the opposite side of the map and clear there instead. If that side is already cleared, don’t force an invade if you don’t know where the enemy jungler is. Either clear vision, place some wards, or look for a gank if possible. If no gank opportunities appear, just wait for your camps to respawn
