You know what, these days everyone love to run alchemist midlane or carry but with no carry items, instead of picking some luxury items that cost a galaxy of gold and have not a very much impact in teamfight and pushing, people used to play a farming alch and become online in 80 mins after the game!
with this build u can join ur team and push towers and take some teamfight, take roshan and go highground, finish the game before the game time reaches 30-35 mins and dont let the other team carry become online!
