Just a quick rant about mastery books
So starting back maple since RED, I have made a DrK. I am now 108 and finally managed to get 14mil total. So I go and buy masterybook 30 to get my dark impale level up. But when I used it it will not work... Now I remembered that I need to use the 20 book before and then the 30 book. I only have 3.9m left and no way to get fast mesos. Guess ill have to wait a long while again.. Ahh well, what do you guys think, should we be able to use the 30 book before the 20 if we desire to do so ? I think so.
