Thoughts on the Patch Notes

There are not many major changes in the patch notes here, but it can’t be crazy content all the time. Axolotis’ haven’t had much love since their introduction, so it’s cool to see them circle back and refine their AI a bit.

Llamas could also use some more love, so if we were going to see a smaller snapshot that just focused on fine-tuning some content, this was a perfect direction to focus on for these patch notes.

Wrapping Up

Surely all of these smaller snapshots have to mean that the next one is going to be huge.. right? Well, here’s to wishful thinking!
