Draven maybe a problem, however he does require the biggest amount of skill compared to all marksmen I believe. The problem isn't only Death's Dance, though that is the biggest offender now. It was the decision in the marksmen update in preseason 6 to let marksmen be able to build 5 or 6 offense items without any problems. This was when Phantom Dancer got that horrible damage reduction passive, Death's Dance creation, and buffing Mercurial Schimitar. Essence Reaver was created giving Marksmen cooldown reduction when Cooldowns were supposed to be their weakness since they have the most powerful auto attacks, now they can have both. Both Sterak's Gage and Maw of Malmortimus were abused. Now Guardian Angel was changed to an AD item. Before all this Bloodthirster got that shield to deny damage and burst even more so.
Giving AD items huge defensive boosts that makes even tanks cry was a horrible mistake. Marksmen at this point get essentilly the best of everything in their items. Massive AD, Lifesteal, shields, cleanse, more crit%, damage reduction, %hp damage, %hp dmg boost with armor pen, grievous wounds, essentially an exclusive revive. At this point it's harder to point out what marksmen don't have in their items. Other than AP and perhaps flat armor shred. Only because marksmen abused armor pen for massive early game power so they can't really use it anymore. Even then they probably still can.
