Now I get why people are complaining about Death's Dance

So I've been looking around the forums and see a lot of threads complaining about Death's Dance, in particular on Draven. I never thought much of it until a match I had where I was facing a Draven who built it. This was me and Draven's build : Me as : The fight started off with us just dancing around then I tried going. Keep in mind this Draven is 3/7 and I'm 7/2. I was able to one shot anyone on his team, including the full tank . I used everything on and he was only at 40%. I actually had to back off while I watched him bleed but lifestealed most of it back. I was actually shocked because by the time I had everything up again I couldn't go in on because I was at 30% and he was at 70% because of minions he lifestealed off of. Nerf this shit this is disgusting.
