DotA 6.73 OFFICIALLY Released!

I don't think her squishiness is in question. Once Drow gets Shadow aka Lothar, she is in my opinion the best character in the game. With an amazing slow that can be used all game, a silence which for any successful team disables are needed, with one of the most overpowered auras in the game, with a HUGE agility stat boost per ultimate level and mixing that all with the computability of an escape method such as Lothar. Not forgetting the fact that she doesn't need to get super fed early like ANTI-MAGE needs to. She only really needs anything that boosts her agility (Treads + Wraith Bands), an escape method + EVEN MORE DAMAGE (Lothar) and then you throw in some more survival + agility + damage (BFLY).

Anti-mage has numerous item builds, but I think going tanky is better. I don't think BFURY is the way to go because you don't need mana regen. It's much easier going Vanguard Vlad S&Y then BFLY OR Heaven's Halberd as it seems to be one of the best items in the game for any agility carry. Which like said before take a lot of kills to farm.

Battle Fury is core on him because none of his skills allow him to farm, the splash damage on auto-attacks accomplishes this and is what allows him to get the items he needs to become the super carry he is known to be. It isn't for the regeneration, which does help him keep farming and retain mana to constantly blink around, it just isn't the main reason.

Without it, Anti-Mage has a tough time farming.
