I don't post often here because of poor experiences with the IH's flame but Hylian blink is really strong on sniper/drow as well as many other heroes, its almost never bad especially if the game will end before you are 6 slotted. You use it to stay away in fights, chase solo heroes escaping or insane split push (more so drow, you just blink to the tree's at any sign or thought of anyone). I have noticed myself building it in more and more situations and on different heroes and finding success with it. I have single handedly won a Drow game because of blink dagger and split pushing when the opposing team all had way's of closing the gap. (PA, QOP, Blink SK, Blink SS, WR). Sometimes you need it just to counter the opposing teams blinks so you can re-create the gap. I have also climbed fairly well out of what most people consider "Elo Hell" but tbh the hell never stops and the retards just keep coming (Like my last ranked game a guy insta locks DK after the draft and skills stun @1). I calibrated at 3887 and then went down to somewhere mid 3600's and then made it up to 4901 and currently I am sitting at 4780. I am fairly certain I can crack leader boards as well I just have to stop tilting when I notice an insanely bad player on my team, as when I do I play worse even down to mechanics like last hitting.
