Until they change it to you only get one clip with a full icebreaker clip when you switch, you are an idiot for not doing it. I get 18 shots when I have 6 bullets in my icebreaker when I switch. That is absurd and I recommend it to anyone else simply because you no longer have to worry about that green box anymore. However, I did go 8-0 with no boons yesterday just sprinting at the opposing team using my doctrine. I just kept my icebreaker equipped since I never needed to snipe lol.
