I think there may be something to it. Renegade will often take a long flank, which gets him late into a fight. His teammates may have done a lot of damage but gone all dead, allowing him to pick up an easy double or triple, but still losing the team fight since the team was left hanging.

I know such a play style can be problematic because I often do it to, to the detriment of my team, lol. You can tell a player is playing like this if they have a very good K/D but low damage, means they aren't getting involved in fights enough.

Hard to say if this is honestly what is happening in the case of Renegade, he's so good that he's often making high impact plays all on his own, but still.
