If it is only barbarian (plus yay for the new hotbar), I might finish my current games first before downloading the patch. Although I hope for Karlach as a companion
They have been teasing fireball (aka. level 5) but then Barbarian smashed ice sculpture of a Mindflayer - so I am not sure if it was a red herring, or if they will also announce level 5. We will see. So far QoL changes already make it my fav updates. Will be diving in to see if there is anything that I can find to complain about.
According to Sven, more UI updates are in production.
