While I note that some characters, both low range and high range are lame in their bloodthirstiness, I'll also state something else...

"The argument that "It didn't really hurt you." - while important to make - still misses the point: Is this fun?"

In any situation where there are the elements of winning, there are the elements of losing. And losing will never be fun, no matter how much you sugar coat it. For the most part, dying isn't that big of a deal, and revenge is far sweeter than many give due credit. The most satisfying experiences I've had in CF was pasting people who thought they could just walk up and bash me down with their 24th "Lowbie Fire Giant Bash Specialist" or LFGBS™ for short.

So my answer to this problem, as my answer is to many other problems, is that the only way to take the power into your own hands is to become able to adequately defend yourself. No amount of Immortal policing can replace that as the best defense mechanism against Quake-style players.
