Stealth Nerf?

I have never posted before in this forum, but i have played since december. I have paid to play... I have 20+ 7 star characters, and I can say that despite all of the changes, I still enjoy this game.

That being said: I just spent over 500 energy, ~200 crystals, on Mk 8 BlasTech Weapon Mod Prototype... I received 2. Seriously?!!

I have had bad days (farming Rey and didn't get a shard).. I have had bad weeks (farming Ewok Elder and didn't get a shard)...

Tell me that this is RNG... If it is... Okay, it was a bad day\week... The odds are teribbly against me (again).

If not, screw this game.

I will not put another dime in to this game.
