The WW2 aircraft in question, much like the WW2 tanks, is also not placed in chronological order. It doesn’t matter that the Duck flew in 1944: with historical MM it would be complete DOA. Like I always say, if you’re fine with one anachronism, you are implicitly accepting the other one too.
The Duck is at 2.0 and 2.3 for the same reason that the Pucara is 4.7. You either accept both or refuse both.
And in a PVP shooter game that requires a large player base to keep lobbies full, you have no credible alternative to performance based MM.
The Southern Cone was considered part of the First World during the Cold War, not the Third. As for gameplay considerations it certainly gives Germany help in a department that needs it.
For those who think it’s a dilution, they can simply not play the vehicle.
If a vehicle exists, it will come to the game. They will never turn down free opportunities to add content. When? Who knows. The game has been going for 14 years. If it was your job to make it last another 14, you also would drip feed content the way they do. There are so many vehicles in WT that we can enjoy those already present while waiting for all of these to be added.
Nothing about the Pucara is low effort, so the word is misapplied.
