How do you beat Rengar on this map? It always seems like he gets 50-60+ more creep kills than everybody else in the match, and if he gets an early kill he snowballs so hard so quickly that we can't react. --- Happy is the most awesome person in the world!
TT in general is more farm intensive, I think. Push the bejesus out of your lane, clear jungle, repeat. Any down time at all can give the other team a huge advantage in gold and experience. I think your problem wasn't Rengar so much as the dynamics of TT.
