Snapshot: World of Tanks Blueprints buffed?

A bit over two years ago World of Tanks introduced blueprints to the game. As you probably know a blueprint fragment reduces the amount of XP needed to unlock a tank. And the blueprints you got were generally random. If RNG drew you a blueprint for a tank you already have unlocked you'll get a Universal or a National blueprint fragment instead.

And that's how it worked for two years. Since I have every line in WoT researched up to Tier IX I piled up a lot of National blueprints that I didn't have any use for.

But recently it seems like something changed...

Lucky World of Tanks RNG or ?

Over the last few weeks it seems like I've been getting a lot more blueprint fragments specifically for tank lines that I'm grinding. In fact, it's been uncanny how often I get awarded a blueprint fragment, and find that it's actually useful. But then, yesterday, was the one that blew my mind. 

I've been grinding the last three tank lines where I didn't have the Tier IX unlocked yet: The VK 100.01(P), the AMX AC 48, and the Lynx 6x6. I've been just finishing the x2 dailies on each of those, and supplementing with some XP boosters. I was getting pretty close on all three. And yesterday I finished a mission that awarded three blueprint fragments. Here's what I got...

That set of blueprints - for exactly the three tanks I was grinding towards - finished all three of them in one swoop. I should have bought a lottery ticket.

Coincidence? Could be. But this, combined with the fact that most the blueprint fragments I've received in the last week or there have been uncannily useful make me wonder if Wargaming tweaked the blueprints generator to try and deliver more useful blueprints.

Have blueprints been more useful for you too? Let us know in the comments below.

GLHF!
