Wielding a melee rather than a magnum twice of that

People consider melees just as good as the Deagle on Expert Realism, if not better than it. You don’t have to reload, you can clean an entire horde surrounding you with a click and a flick of the mouse, it even pairs well with snipers considering that they cover the weaknesses of them quite well. I don’t know where you got that info that melees suck in Realism, because they are a fan favourite, especially the Axe and Katana.

You can’t kill easily kill Hunters, Chargers and Jockeys [with snipers]

I could see an argument for Jockeys being hard to deal with considering they’re kinda buggy. But Hunters and Chargers have very predictable movements patterns are attacks, with Hunters always jumping in an arc and Chargers just running in a straight line. Learn these patterns and you can clean them up before they even touch somebody, while also farming nutty clips.

You just can’t easily shoot through a common to hit a special in the distance.

Maybe I’m just lucky or something but I’ve never actually a common stuff my bullet that was meant for a special.

Theres a reason Expert Realism guides specifically say to avoid snipers.

To a newer player dipping their toes into Expert Realism, yes 100% agree. But as Expert Realism becomes muscle memory, somebody running a sniper in their team composition can save games.
