I was watching a level cap video where he saying grenade spam is bad. Personally I enjoy the grenades. I remember yesterday I was playing operations and everyone was throwing grenades and I was literally giggling at all the chaos and was having a good time.
Towards the end of bf4 I only really played locker as it was so loud and alive and just an all out brawl.
I think people who say things like it is the will of the whole community are a bit deluded. Different people find fun in different things.
