Holy Fuck.
I was in Siege of Shagnhai - Conquest Large - 64 with NOBODY there. I spent like 15 minutes or so trying to figure out how to bring down the tower. Took A LOT of hits with the M1 Abrams main gun to weaken the support pillars. Never done this before plus I had no idea exactly where to hit. Just kept trying to destroy 3 different supports.
Then I could hear it was about to collapse, and then it did. I was fumbling to back the tank out and also try to get out of the tank so I could see the collapse but I hit the wrong button. Amazingly the server did not crash.
I died in the collapse but then took one of the choppers out to see if I could see anything. Tons of smoke (no framerate dips that I can speak of) Then I crashed the chopper into the water. I must have been there for 20 min cause I started typing this and eventually idled out of the server. Sadly, I didn't get to see what the building collapse really looked like but that was my fault for not getting out of the damn way in time.
Again, to have much chance of getting into Conquest, and to have a decent MP experience in other modes in general, you have to use Battlelog on another device to connect PS4 servers. I don't own a tablet so i just use a cheap laptop. I refuse to even attempt trying to get in by just directly using PS4 on its own.
