A couple changes may be made to the items. For starting items you may way to go with boots of speed and 3 health potions. Either Mercury's Treads or Ninja Tabi work for boots. Get whatever you think will help the team out most. If you are having a lot of trouble against AP carries, go with a Hexdrinker instead of Atma's Impaler. Instead of Bloodthirster, you can get a Frozen Mallet. And lastly, instead of Force of Nature you can substitute it with Banshees Veil.
