You could really make yourself a specialized, focused type of killer that was very heavily anti-tank, or anti personnel, and the choices for this path in BF4 so far seem very weak compared with BC2.
I must have launched 20 40mm grenades in my last game and killed no one. I really missed the ‘increased explosives’ damage from BC2 about then.
In a way, these things are still present via the specialization - this time around you just depend a lot more on your squad in terms of getting them though.
I loved the increased explosive damage. At the time I was playing on my laptop w/o a mouse and I wasn’t a great shooter. As soon as I picked up that perk, I equipped a rocket launcher and went to town. No one was safe since I could one hit kill people.
I should have clarified - those two specifically don’t exist, but there are items that let you carry more explosives which, in a way, gives you more explosive damage in total.
