Roadhog
Roadhog’s inclusion on this list is easy to explain—hooking enemies will never be this easy in Overwatch again. We are now past the ages when Roadhog could snatch enemies through walls or have them magically get pulled towards his hook despite the fact that he overshot them a little bit. Now, hooking enemies can actually be a challenge for a player who was relying on these bugs before.
In the Low Gravity brawl, hooking enemies is essentially set on easy mode. Again, heroes who are slowly dropping to the ground become easy picks for Roadhog’s hook. The best part is, if you hook an enemy from the air, the hook actually stops some characters a few inches above the ground rather than placing them on the ground. This means they have a split second of limited mobility before they can plan a daring escape. By then, a solid Roadhog player would have already delivered the final blow to squishy heroes.
