Haven't really noticed it before that you can buy 50% exp for different things. 1 of them as many of you know is 50% exp boost for like 1hour (?) for like 125 or 150 gems, I can't remember. Anyway, I wonder how many will spend money on that, or will you play normal without any kind of boost because you think it's a lot more fun and challenging and you won't rush your levels anyway so it's just a waste. That's at least what I think about it.
How about you?
