So there's a gems promotion (up to 30% off) at the moment and I'm considering buying some for the future. However, I was talking to a friend who plays the game as well, and we both sort of have the feeling that it's actually cheaper to buy the character promotions (which most of the time consist of "character X + Y gems") rather than buy premium characters with gems. Even with the current promo the character promotions seem cheaper.
I'm guessing people on this forum buy either character promotions or gems (or both) and I'm wondering if we're correct or not?
Also, I'm tired so my apologies if my questions don't make a lot of sense.
[EDIT] I should perhaps mention that I live in Europe and I'm not sure that the rates and prices are the same here.
