Notes: The playable characters can be purchased via the in-game currency RP, which can be purchased through the in-game store. The in-game store is built with casino elements, such as RNG loot boxes and purchasable currency, but the developers have stated that they have a system in place for continuous balancing and preventing power creep. In the history of the game however, some skins had better abilities compared to the default characters.
The monetization is pretty reasonable, you mostly pay for cosmetics, however I remember that I was furious when they had removed rune pages, for which I had paid a lot for that time.
IMHO there always seem to be a conflict with monetization for games that are updated regularly & the updates result in a dramatic change of gameplay.
