Riot Games has consistently included an economy trait within each Teamfight Tactics set. But the Set Nine Piltover trait has had trouble living up to what players want from an economy trait, potentially paving the way for a rework.
Econ traits in TFT typically reward players for running an early game loss streak, providing a variety of loot upon winning a combat round. The Piltover trait in TFT Set Nine drops loot and summons a T-Hex to join in the battle, with the dinosaur gaining Energy charges that get converted into power upon winning a round. Having to choose between loot drops and keeping T-Hex on the battlefield has been causing issues for some players, according to game designer Stephen “Mortdog” Mortimer, leading to an upcoming rework.
