However. There are logs of certain very powered characters, facing these large gangs solo...and not only surviving, but kicking ass.

They can do that because they're skilled players, often times with the right race/class for the right situation, with the ability to exploit their advantages and minimize their weaknesses. Believe me, there are plenty of times where a paladin or a lich has been slaughtered by one guy, let alone a group of four.

The reason you hear about (and see logs posted about) the ones that can do what you're talking about, is because it's extrodinary and rare. We definitely don't want to handicap that.
