Common.... who's with me?
If they want to give me 50% of what I paid for it back, then I'm 100% with you.
I corrected your typo: I assume you meant 50% off the pack price, not getting 50% of the pack...
Engaging smug mode...
if you give back all the bonus resources that you gained from it till the time of this discount?
50% of it, sure
Adjusted the title so it doesn't look like an official news announcement. Was: "Easter flash sale: 50% off Deathknight pack".
Tsss... instead of just making it official
