Hello people :) !
I've a suggestion for the game:
The idea is that each class can have 2 skill builds, which the player could change at any time, at the price of a orb,or something like that, so each player could have a "hybrid" character, that is, with PvP and PvE build.
So, the price of the Book of Oblivion would decrease a bit, since it would be only used for mistakes, and a new item for changing the active build would appear in the miracle shop, with the price of 10-20 miracle coins, or something like that.
Hope you like and consider my suggestion. :)
