Maybe its just a me thing but I've been duoing with a controler player and they have same rr gains as me if not even better while usually being bellow me on the scoreboard I'm talking around 10kills every game so that means that utility is being at least kinda taken into consideration.

Also, I don't mean to downplay any roles here but at least in a soloq enviroment your duelist is gonna be the reason you win/lose most games. If you have a duelist who can't entry for his life or perma lurks with a good controller you will struggle. If you have a duelist who gets an entry frag 80% of the time you could have a controller who refuses to press smoke and it's still winable.

Another thing is the fact that duelist players can't provide much apart from kills and pressure when going into a site so if you are outmatched in a game normaly the duelist will finish with the worst score and tank a -25+ rr loss while the rest of the players will usualy lose less. You can't expect to get the highs without the lows. A duelist only climbs faster when they have a huge winrate if you are stuck at 50% +27/-23 per game or +21/-17 really does not make much of a differance.

To me it just sounds like people want huge rr gains without any other downside of being a duelist (doubt it will ever happen ).
