When's the best time to face the lesser high skilled players sometime this week or later?
It’s completely random
I remember someone posted something about this a couple of years ago, and he broke down the days, times, and opponent levels, etc...Of course he received a lot of negative feedback from the community...lol.
From my own experience, in "normal years", playing on weekends will give you a greater pool of players to match up against, which is good. I also have noticed that playing late night/early mornings you will have an increased chance, unfortunately, to play someone over seas, like in Korea, in which the gameplay is terrible due to network latency.
If I had a good answer to this question, I would have a much better record.
If you have insomnia and find yourself up in the wee-wee hours of the night, do not play RS. I do well until about 1 AM. After that it seems like only the hardcore no-lifers are in queue.
