I feel dirty

I normally play the support role (I primary jungle secondary support, so mostly support), and when I jungle I play tanky carry junglers like Shyvana (My favorite jungle since early season 3). But Riot released that new item and I have a crap load of Kha'Zix experience from when they released Stormraider's Surge and I thought it would be super op, so I decided to dust off the bug and try it out. I had a couple of great early game ganks that ended up paying for a fairly early Duskblade. At that point I started playing terribly, going for non islated targets, q'ing targets just before isolation range / etc... but I kept getting the kills anyways. I was making serious errors that should have cost me not only the kill but also my life, and I was being rewardly richly irregardless. It feels icky doing well when I know I played poorly. Now I can only imagine Duskblade on champions with more severe burst and redundancy in their kits ( )
