If you didnt but Stalingrad FAP, you literally get nothing to lose. Most of the things will be carried over.
But if you bought Stalingrad FAP, you will lose most of the paid content, most of the FAP will not be carried over.
Same for Pacific FAP, you only get 4 premium squads left, all others special perks will be gone. But at least there’re 4 useful squads, instead of 2 wasted flamethrower tanks. And F2Pers get most of the stuff.
Also, what’s more freaking ridiculous, you have to of grind hundreds squad levels to let you upgrade the soon to be EOLed weapons and tanks, as there will be no tech tree to enable you to level weapons up.
And lots of paid to skip campaign levels, squad levels, or even orders , will soon be greatly de-valued.
While F2Pers, really get nothing to lose. All those “special” stuff will one day be on shelve or event again.
I bought 20 of the Thompson, 20 of the 9mm PPSh, and 36 of the Manlickers because I may want to swap them in at some later point for variety and I had the silver sitting around
