The Magic Find (MF) mechanic inflates items drop. Since the game economy is intended to promote item trading among players, MF allows players to acquire too many items, leading to frequent sales at minimum prices.
Combined with the ability to summon one's own character in Reinforcement, this mechanic risks destabilizing the in-game economy, which is meant to be driven by player-to-player item exchanges.
This proposal suggests prohibiting the use of MF skills and items in Reinforcement to protect and sustain a balanced item market.
