I will not lie, I think that is the best deal they have ever had on gems.
Even 50 gems for 2k ngold is not as good as that.

I don't buy gems, but it is tempting.

The probably is, I will never refill that much. and if I am going to spend money for the gacha, I am going to do the daily deals.... maybe... that is 3 gacha rolls... no, I could get 5 dressblooms for that price... but the refills... no pull yourself together, you don't need it.
