Set 2 is closing in on its end in Teamfight Tactics. As the developers announced in January, Set 3 will go live somewhere around mid-March. New champions, new traits and origins and probably new items will flood the auto battler. However, until then, the development team is mostly focused on tweaking Set 2 minimally. Keep things in check, as they say, and hope the meta stays fresh. In patch 10.4, which goes live later this week, Riot Games is making very few adjustments.
