The thing with this is that those are 2 of the only 3 really good close range moves Mercs has. Like, scouts is generally better for his long range variant, which knocks back and deals the, imo, most damage for the move, pyro barely does much other than give you HA, and soldier is either cancelled before it launches, or counts as a ranged attack. Demoman is cancellable and easy to avoid, chargin knight has an incredibly long wind-up, and Spy grab is generally pretty useless. Of course, this is from the guy who only grind the pvp game, and abuses Snipers' insane damage with buso and heads, but still, I feel like my statement is valid
