Darkflow appears to be pretty much a sockpuppet of Gaijin. It is therefore to be expected that their financial guys will TRY to gradually squeeze players to test how far they can go, since that’s what they have been doing so far with War Thunder and their other games, and so far it worked good enough for them.
What we should hope, is for them to realize that this isn’t WT and, as you already said, they can’t enjoy monopoly in the FPS market… And they’d better realize that BEFORE the game reaches a no-going-back point of bleeding playerbase.
Anyway, I’ll enjoy it till it lasts. I’ve only spent premium currency I previously earned in WT so far, and I plan to keep on this way. If one day this goes down the drain, I lose nothing.
