A very simple idea to drastically reduce the amount of grind. Remember when the weapon transfer mechanic was introduced: Boosted progress and custom battle rules - News - Enlisted?
Yea, so my idea is to expand that mechanics two ways, and also propose two ways of doing it - one, less radical, would be to only implement the first option, and the second one would be to implement both of them.
Option 1
OK, the first option is the smaller one - It’s just about allowing the transfer of a weapon into the campaign that weapon exists in, but where you haven’t unlocked it yet. It would not reduce the amount of grind, but would pretty much completely eliminate the repetitive unlocks problem. It’s basically about eliminating this:
Option 2
This one is more radical, but it would both completely eliminate the repetitive unlocks problem and shorten the grind. The idea is that unlocking weapon in one campaign would skip that unlock (researching the whole level with that weapon) in all campaigns. It would of course only apply to the levels that unlock just the weapon, not if they give you a squad and a weapon (these levels’ grind could be halved instead). So it would look somewhat like this:
I have unlocked the Gew 41(W) in Stalingrad…
…so in Moscow I would have this level half grinded.
And now if the weapon would be unlocked without the squad. I have the Király 39M in Stalingrad…
…so in Moscow I would have this level fully grinded and the weapon unlocked.
