I recently bought the Zephyr Rescue Pack... I thought it was a good deal. I have recently been lucky with BL Scraps (I had 3) and thought 15 cheap keys would get me much closer to 10. I was right, it did. I got 5 from 16 chests. I key-farmed another and was on 9/10 so I decide to buy a key straight from the TP as they are currently discounted. Not only did I not get a scrap but I got 5 Custom Arena tokens.
I never do sPvP. I had done it 4 times in 18 months. It's a truly crappy reward in the vein of Glory Boosters. I was freaking FURIOUS!
