Absolutely right. Kills tell you something about a player, as does damage, but neither is a direct indication of "skill" in the game, unless one completely forgets that the game type includes an object, and that objective is to be the last man standing. That can be done with a minimum of both kills and damage, including, as you pointed out, sometimes NO kills or damage. Most players wouldn't get much satisfaction from a low-damage, low-kill match, but it's efficient and it's lower risk. Unless you need the practice then the best course of action will always be to survive at the edges and start playing when there are only three squads left. That will edge up a player's win rate. Which, imo, is the ONLY stat in the game that I personally have any use for.
But stats are stats and people will always want to measure themselves and will always value most the one they're best at. Human nature.
