Ballistic Focus is fine with most people, it's Double Ballistics that a lot of people don't like.
Accursed hated reviled perk. Especially with usp headshots. Without damage perks the usp rocks, just add stabilizer and pull some headshots. It shreds. :/
Sorry if I am to.....outspoken of my opinions. I have nothing against players that use Ballistics focus, I just dislike playing against them when they use such a perk. So I will find a more... suitable and balanced match when that type of predicament occurs.
