After more experience with the game online (Finally Master Sergeant... after about 4 hours of play time, yeah I don't get to play much my Fiancee seems to want me to do things like the dishes now and then after working, women...), and playing with the sensitivity levels a lot, I think I'm OK with the aiming/deadzone system now.
I've developed a new hate for one game mechanic online, the dropped spawn points.
I was playing a map at Radec Academy last night, and during a search and destroy match both teams dropped spawn points in one little room where a target was. It was just completely ridiculous, between the 30 bodies in the room and all of the bomb smoke it was impossible to see what was going on - all strategy went out the window and it just became a spawn, toss grenades, blindly shoot shotgun game until you're dead mess.
Now, granted, during that match I made more points than I've ever seen in a game before ... it ended up netting me almost 90 points, but still... it seemed to to totally take away from the game.
I also hate it when the other team puts a spawn point right next to your camp. Results in the same run and gun circus. I think they need to introduce more restrictions for where spawn points can be dropped. A larger area away from the other teams camp and perhaps a first come first serve system of disabling the dropping of spawn points within a certain radius of where another teams spawn point is already dropped.
Also, is it just me or is the SMG almost totally useless in MP? After first unlocking it, I tried it out for a game and it seemed like I could never hold it on someone long enough to survive before they blew me away with the standard assault rifle in a second.
RE: Shotgun auto lock, I believe on the official forums they said that they have done something to "fix" the shotgun aim assist. The amount of assist on that thing is ridiculous.
Shotgun Aim Assist
Investigating the problem and will patch it up. Update: Fixed in next patch.
