I think people might preffer broken builds because this version of the game is not perfect, and therefor very difficult. I played for ~30 runs, failing to finish the game, when I thought I had very good builds I was proud of. Then, I tried that Wizard Hat + Mage Robes build, and I won in 2 tries. Of course I enjoyed the broken build, and the challenge to accomplish it. But I'd have preffered if my personal decisions were more rewarding.
EDIT: There's no such thing as perfect, nobody expects perfect, otherwise evolution wouldn't exist, but I think you understand what I mean. Maybe expecting to beat the game in 30 runs is a bad expectation. Maybe beating it in 50 runs would be more enjoyable if there'd be character choices or something, to "try different things", give an illusion of control over the retries.
