Em, I believe we did... Like, two years ago or sth? It's kind of an obvious thing to do, we should implement Builders as soon as possible. It may sound surprising for the newcomers that we've yet to implement those new bots but instead tried to implement a new gamemode (Code Battles), which works not that well for the time being (and makes almost no sense at all without the Builders). It's probably not the best place to whine about it though, sorry :>
