I wouldn't say the maps are too big. Some are downright tiny, but I am finding that they seem to be pretty darn good. They have multiple attack routes and aren't nearly as cluttered as MW3. Head Glitchers don't have the advantage they had in past games, I have been able to take them out pretty quickly in this game.
The key seems to be map knowledge and awareness. It sounds trite, but play Custom Games against the bots and get the flow of the maps. You will find yourself checking the sight lines and it will surprise you how many times you win one on ones because you are prepared, knowing the potential camper spots.
There will always be campers, you just have to outsmart them.
The maps are not too big, they are actually smaller than the maps from most of the other games. So if you think these are too big than something is wrong with you. And people are always going to camp no matter what is done.
There is no need to make smaller maps, just so you can have more red dots to hunt closer, nor are they ever going to make a completely non-campable map ever.
I bet you are an adrenaline junky that needs to have a kill fed to you ever 2.5 seconds or the map is too big for you.
I find it funny you call yourself and extreme-Pro gamer when your rant proves exactly the opposite. A true gamer would be able to adapt and not have problems at all in this game.
So really you need to sort it out; because they are not going to make the maps smaller just to suit you.
Then again you could be a troll and just trolling because you do not like how small the maps are, either way your post is full of fail.
