I disagree with spotting and open weapons.
Medic did fine in bc2 with lmg, it's fine, you can equip a carbine too or a dmr, it's not really restricted is it.
Spotting is too easy especially for recons, I played some BFV last night and forgot how much I detested the lack of spotting but BF6 is taking it too far the other way, manually pressing a button to spot or using gadgets like the tugs should be the only way to 3d spot people, why run a suppressor when it won't make any difference.
Assault get the BF6 version of Paik's wall hack which is a horrible mechanic in a game that is meant to be grounded.
