If it was the soldier update coming this way I might actually play some soldier for once, just to check out the new weapons.
Anyway, even if I don't play that much of either three remaining classes that much I still much wonder what unlocks they'll get, or rather if they'll get any different weapons instead of the -50% on random attribute and +25% on another random attribute sidegrades weapon

well in regards to the new system, you could just wait till you get given the new weapons if you dont want to farm
