Actually I think it's better- previously it would have been the guy in the window dying outright, then the next guy who took his place, so on and so forth.
Now it's spread out, so you can retreat and heal up for no cost. Rate of damage taken overall should be the same.
i was allways like that. but before they lasted longer (bullshit longer thats why it needed the nerf). the trade off of buildings was supposed to be less damage for more survivability, right now its less damage and less survivabilty, right now they are pretty much worthless. only good for mgs so they auto switch sides and become harder to flank.
