It's annoying that no matter how many times you buy a box still you might not get all the prizes.It's obvious "box openers" are the players that more likely are gems buyers. Those should be treated differently from regular players (those who had never and never would spend $ on this game).
So get us, gem buyers, an option - open a box for 500gems and get all staff from it. All 4ths, all 3rds, 2nds and the 1st. This offer would definitely tempt me.
I, as gem buyer, won't open one particular box more than 10-15 times. It's my limit, I don't have "money tree" nor I'm wealthy, just regular citizen with average income, but I do like this game, for the most of the time it's fun to play, decorate and such, so I wish for you TL all the best.
So let's get back to the topic, so 24gem*10 (the average number of opening the box) = 240gems. So 500gems sounds like a pretty good deal for you. Trust me. Some of us, gem buyers, would fall for that. I know I would. .____.
