Wow all about class balance that why need BF4 class balance back so those upstart support players get the second rate weapons again. It just not fair as a killing machine every player now has just as much advantage as me.
Why did Engineer run Carbine/DMR? Why did Recon run Carbines/shotguns? Yet Assault only ran AR? Hmm I wonder.
As for gadgets which every BF has been getting less new gadgets and some class are the dumping ground while others could have more but making a class the Meta seems to be the goal for some rather then fair balance.
Specialist allow new gadgets to be added without it being a requirement to carry something else. Like in past BF your Support you should always carry ammo or your Medic you should also have paddles and health so all they are feeds to others. That scares so many that they may have to do those roles now. I like the idea we could see skis, NVG or scuba as possible new gadgets on top of wingsuits without making a single class the Meta across all BF042 maps.
That is the point specialist allow new gadgets for team roles if you choose and if you want to be Rambo you can go ahead too but you can't expect others to be your feeder.
