Thrower Game Plan
Grom is strongest when played like a thrower: choose fights around Heist, hold useful angles, and avoid forcing low-value duels before the objective is ready.

Watch for Mortis or Leon. If those brawlers appear, play slower, use cover more carefully, and let teammates create the first opening.
MATCHUP
