Mastiff is so ridiculously inconsistent

You should be banned just for picking one up... Its because your just hitting the outer most edge of the massively overpowered gun that doesnt belong in fps at all which is testament to how completely broken it is you shoul be hitting absolutely nothing if the shots off

There is nothing really wrong with the Mastiff. It's the hit reg in this game.  The hit reg is possibly the worst of any game I have ever played in almost 30 years of playing games. Feels like early quake days. 

its wrong put mastiff in normal pool.

@Acumental Not to be toxic, but you're just bad. I've played BF4 and the hit region is actually bad from a time when 30hz server update rate was acceptable. This game is really good because it's made in Source
