Portal - classes

Honestly none of us know anything about how this will be in the Portal because EA have so far shared and said nothing on this specific subject of weapons progression.  
Sad, but how EA have played their marketing cards so far.  🙁

So all speculation from my side, but I would think that we will all start from just the default base load out, no matter which BF game soldier type we select to play with.  And that only kills or XP gained with playing with a specific weapon will count towards unlocking more accessories for that weapon.  (that appears to be the weapons unlock mechanic for the BF2042 core game area, so think they will rely on same for the Portal BF remasters)

Please also note that not all weapons from aka BF3 will be available to our soldiers in the Portal.  Only a select subset of all primary weapons, secondary weapons and gadgets from the original BF3 appear to be in the game.  Same as well with weaponry from the BF1942 and BFBC2 worlds...
