No Hex Key after a long pause from the game

Pretty much the title say all.

Took a pause from the game ( dropped it slowly till on march i stopped to play at all ) and just yesterday i got a bit of free time and decided to play again.

I still remember Keys frag where hard to get, but I won 8-10 matches in the last 2 days and didn't drop a single piece.

There is bug or i just remember it wrong and they where harder to get?
