The title pretty much says it all. It would be really nice if someone who has the information could tell us the exact number of skill points that are available in each area - that would help tremendously with character planning. For example, in the starting area of AD, I believe you could get 2 skill ups from sky shards and then 'x' number of skill ups from quest rewards, so all in all, when you complete this area, you will have 'x' number of skill ups at your disposal.
The intent isn't to provide much of a spoiler as it is to outline what to expect in the way of skill ups. It's also a little difficult to collect that information without spoiling everything to come, so if someone who already knows what lies in store wanted to donate some time, that would be awesome! Make sense, I hope?
