edit: Darius deals crazy base damage, so right now it's fairly popular to build pure tanking on him because he does enough damage anyway. His ult does 425-830 true damage at level 18 without any stats whatsoever, and cools down instantly if it kills the target. This makes him really really good at chain finishing, making him one of the top champs for locking in multkills. It only counts as stealing if you think that dealing 2500 true damage in 4 seconds is not a valid contribution to the team, or if you think that stealing is somehow bad when the champion is explicitly designed to lock in kills for the team.
So now a story:
I played one game late December 24th, and decided to play one of my absolute worst champions to get some practice in, trying out a new build and strategy. My entire team for the most part picked people to support me really well (only coincidentally; I was last to pick).
In the first full teamfight I got a quadra kill and they got aced. In the next teamfight I got a quadra kill and they got aced. I went 12/0/6 and we won at 30 minutes. Now, I couldn't tell you how many times I've gotten zero deaths with a non-support in a full-length game, but after almost 2,000 matches you could probably count it on one hand. Mind you this is with one of my absolute garbage-tier champs that I couldn't figure out how to play/build properly.
It was a Christmas miracle.
Merry Christmas everybody!
