TLV is a definite contender though. Obviously the stats will be heavily influenced by which heroes are on the free rotation, but I think TLV will always be up there. He's just too
different for people to buy without testing first, and most people that test him hate them.
I think Stitches, Chen and ETC all have low popularity rates because they're just super-weak heroes. DotA has taught me that people
love hook mechanics, so it's amazing to see that Stitches is so unpopular. I know it's because he's a dreadful hero, but it's still surprising.
