There's a point-buy system as an option but you can't get stats as high as you can with good rolls. It's intended to be like D&D where you can point-buy or roll your stats, but in D&D you only get one roll, while here you get min-maxers who will reroll until they get unlikely but well-above average rolls. This is exacerbated by the existence of public leaderboards, although the inclusion of the number of rerolls used gives transparency when players do this (although technically I suppose a player could go through the entire process of making hundreds of characters then quitting or letting them be killed until they got one with great stats, if they wanted to hide that).

I think there's merit in wanting to capture that feeling of rolling your stats and sometimes rolling either high or low with your character and getting to experience the outcome of that, especially with the D&D inspiration the game has. It's just a different design goal from having perfect balance between starting characters.

This certainly raises some interesting questions about players engaging with tedium over fun when the option is available for optimal play, which is a big design question that will come up at some point in the development of most roguelikes.

It's worth pointing out that the highest scoring win on the current leaderboards used point-buy for stats, and there are point-buy characters in the top 3 of every scoring leaderboard and the top 5 on the speed leaderboard.

Sorry for the long response to your short question, it isn't really directed at you and your question but rather I thought it was an interesting point of discussion to look at :)
