Before when i got blueprint i reveived random blueprint (4-10 tier). I always wanted to get 8-10 tier just for the value of 10k+ exp. But now roufly after 1.13 i always receive 4-5 tiers (about 10 blueprints). And now i ask, was there a change that blueprints will always drop for lowest tier tank i can unlock or am i unlucky as hell? (and if its changed like that how can i get universal blueprints except for BP?
