Over twenty minutes had passed, but the first tower still stood for either side, down in the Bottom lane. With the rapid pace of high-level games, this was a rather uncommon sight.
The Bottom-lane pairs of both teams could no longer remain farming in their lane. Part of this was because they had reached the point where whole-team assaults on enemy towers would be the key to victory, but another reason was the need to be ready to contest for Baron Nashor, which precluded the ADC from remaining in the Bottom lane.
(Translator's Note: Baron Nashor is located in the Northwestern part of the map, while the Bottom lane spans the Southeastern corner, i.e. the opposite end of the map.
