I was discussing this same thing with my friend. To me, it seems like the things they put in place to be anti-"camper" actually help reinforce that gameplay style of holding one spot down. Instead of one person of the Meltdown building, you have a sniper with two betties and a shock charge, a guy hiding behind the desk in the lobby, someone laying down next to the vent ladder incase a bettie goes off, and snipers on each side of the building, one behind the truck and one facing the reactor building incase of someone taking the long flank. The whole team sits. And they have that wonderful thing in the middle making you come up directly into sniper sights.
This is a playstyle that seems more prevalent on the maps. They hold down one half. Hijacked, Aftermath, Meltdown, etc. Which some would argue is great team strategy, and I will admit it is, no doubt. It's just not fun.
Especially with something like Hijacked. Sure, you can use the under the boat path, but you exit RIGHT at their spawn, so if you want to get those guys sitting at the pillars, you have to turn your back to their spawn.
Then you have things like the target finders to help a camper see the people they might normally miss. Just light them up with a red diamond!
It just seems like it's facilitating less movement and more defense, which might be fun for some, but I gather that it's not fun for most. At least from all the bitching I hear in-lobby and online (myself included).
