From the Fanbyte interview:
So, apparently, we're not necessarily going to get them alternating every level. Given the setup, i'd expect Class to be more frontloaded while spec is more backloaded (since class tree mostly covers your toolkit that you kinda need)As you level up, there is a schedule that we have laid out on our end of which type of point you are going to get at which level. I'm going to make up numbers here but at level 37, you might get a Druid points, at level 38, get a Resto point, at 39 and 40 Druid points and 41 and 42 Resto points.
