Knowing Relic an increase in drop rate is only going to occur if all other options have failed. So expect that in 3 months minumum.
I thought of point 4 aswell, its one of the options that makes the most sense as long as the interval between each commander drop isnt absurdly long.
Totally agree on point 5 but they wont change it. You will unlock everything within a month as a casual player because all Rus&Ost bulletins were unlocked for everybody (bad decision). So thats never gonna happen.
EDIT: They should never have put the 3 new commanders on USF and OKW in war spoils. When CoH2 came out it came with 5-6 commanders on each side, giving the game some extra strategic value combined with bulletins. Now your stuck with no variety in commanders until you get extremely lucky. And even if you do play 200 hours, it doesnt guarentee you anything because of the damn doubles.
Relic has made an art out of alienating its fanbase. CoH2 came out with no Leaderboards or basic match which did its fair share of damage. Now this mess of War Spoils, which as it is are only for the most hardcore of the hardcore players if you want all new commanders/skins/bulletins.
Man, I lost an hour and half game because of this crap. I got a king tiger, got 40 kills and vet 3 in 5-10 minutes. When all of a sudden it gets one-shotted by a stolen Pupshit at 5/6 of its health. Amazing how they can still drop the ball this hard.
