I don't think Drow would ever be picked after that idiotic nerf. Squishy, low armor. Frost arrows is pretty good and Silence is pretty good, but neither do damage (competitive is and almost has always been all about nukes). She kind of has push/antipush, but not really. If she was drafted with an 4/5 or all ranged team w/ Enigma than maybe, dunno if it would be worth wasting second phase ban Drow if you could see it coming.
It's piss easy to get in 375 range and a lot of popular heroes such as Magnus, Gyrocopter, Rubick, Shadow Demon and Nyx accomplish this instantly, instantly taking away Drow's ultimate which doesn't happen for much other heroes in the game.
A true hero never wavers. My place is at the top. Bring me a real challenge.CHA
