I wonder me if anybody know an site where are compares of the costs from free MMORPGs?
As example: At every expansion get PW more expensive. As example: since the last Expansion are much stronger towers, these take more HP from the players, so the players have a longer TW and need more Charms. The charms are 50% expensiver as an half year ago.
Or more Skills means more pay items needed. (one of the last expansions).
