There has to be a mistake with this new skill boost for exp. You geht a maximum of worht of 6000, thats the playtime of 1 mission in higher levels and have to pay 780 points. And then you have added a commendation xp boost there you get 10000 xp that cost less (and 10000 comendation xp is far more difficult to achieve).
I do not want to start a discussion, i know some people would think that this is planned and is for people who want to spend money but these numbers do not fit to a model there you can gain money with it. Only people who do not understand that this really means would try such items out. Perhaps there was a mistake with this change ? (before todays patch there was an hourly xp boost i think, im not one of the persons who use the c-shop regulary).
