I was thinking now with an ELO system instead of points we don't need to cap the amount of duels per week, right?
Yeah, no need to cap duels with elo. There may be some incentive to still cap facing same opponent though per some period of time. I definitely had to prevent people from deliberately feeding wins to players when I reffed it ages ago if they didn't care about their own rating.
If challenges are allowed that have to be accepted, it may create some similar trolling. I.e. a good player could tank their elo on purpose before challenging people they don't like just to drag them down.
In the long run, all these things kinda just work themselves out as long as most people duel many different players many times, so it depends on how much people engage with it in a fair/reasonable way.
