Timbersaw is a great hero who fits into a lot of different lane setups! You can offlane, or safe farm(even mid!)!
He gets really strong at level 6 because of his mana inexpensive ulti that lets you harass opponents out of lane, and set up kills! He scales well late because of pure damage, and is a really high aggression hero who is quite tanky.
You have to be generally passive before level 6, but once you get some levels and mana regen, the hero is SERIOUSLY fun!youtube.com/PurgeGamers
