Or is it just that those who break Dragon Utopia on the 2nd week don't get into the beginners' tournament?

Dariel took a three-stack on the second week in a game with me. And he lost in the tournament :)
What makes you think readmе is a strong player? Well, sure, overall he normally executed a good layout in a game against a beginner. I didn't see anything particularly strong in the report. It's pleasant to play when you have cons within reach for 1+2+2+2 angels :) I think most of the beginners here would break a two-stack con on the second week.
Regarding RiMpel2. A three-angel con on the second week is broken by any Castle under normal layout. With a good layout, even a own-race one breaks it. I don't remember what I was supposed to see in Rimpel's game.. Honestly. Even if I did, I don't remember such trifles

If I don't take them, then who should I take? Only those who run around with a single hero on the wasteland? Firstly, there are few of those left. Secondly, that way they will never learn anything

The tournament may be for "Новичок", but it is still a tournament. And its winner must be worthy of wearing the medal. Sorry, but I don't hand out medals randomly or for nothing...
