I like the TTK. A lot. It means you need to move carefully, peak carefully, and sometimes not fire so as to not draw attention to yourself. Good stuff.
What I don't like are the explosives. With the TTK as quick as it is, the explosives have to go. Or they have to be toned WAAAAAAAAY down as far as splash damage is concerned. I get nuked way too often by RPGs, mortars, flying C4, etc. And it ruins my experience.
I know the explosives are needed for the vehicles. Cool. Let's tone the splash damage down in infantry, please?
