Junkrat was OP according to Junkrat mains before the nerfs, now he can’t just keep spamming decent teams and expect to get his tire every 2 minutes, oneshotting anyone with mines whoever comes close (without really aiming at them).
He’s fine. A bit situational, but hey, isn’t Doomfist as well? Both of them work best in tight corridors and less great in large open areas.
