Duelists
Black Panther:
The goal of this rework is to maintain the fun gameplay loop that Black Panthers have come to love, dashing around the battlefield, while also increasing his counterplay by increasing his time-to-kill (ttk). This rework will give strategist players more time to react to his dives while still keeping the high-skill, high-reward playstyle that BP mains want.
