All those ideas about "nerfing" weapons will not help. Problem lies not in them, but in human psychology. Removing player lvl and cach info could help, but it would not get rid of this problem entierly, since people still can find themselves a more dangerous target after some time. And it affects not just one guy who wins time after time, but entire groups of people, and thats, in my opinion, weights the ingame "balance" by itself. Yes, Such people like Decap might not like "targeting", but this is one of the ways to 'balance out" the game. Noone would like seeing one guy\team winning each and every game, right? Thats the balance of it. Still, I can give you an idea to balance "winning streaks" by decreasing prop limit of a winning player. Each time (after 3 wins or so), winning player\team will experience "prop farigue", which will decrease existing prop limit by 1(or 2) every time they win a match. This will hold on to them as long as they winning, and will disappear after 3 rounds without winning streaks. This (i hope) will help losing players to catch up and give some winners small "time out".
