Larian really should have mentioned that your AB points per level increase to 2 once you reach level 6, and increase again to 3 once you reach level 11 or 16 (I'm not sure which).
Reflexes hasn't yet been removed from char creation, but it will.
I did read that after posting still it sucks to gain a level and not be able to get better at a skill you already know. Still with those additional points in the mix it still does not seem like enough skill points really. (Unless I am unaware of something that adds skill points besides levels)
A Level 20 character will then earn 44 skill points (49 if we count the 5 at creation). Shouldn't a level 20 character be masterful? But consider making a Master Thief: 5 in Pick Locks Pick Pocket and Stealth. It would take just about every point available with very little left over to make the character say charming or lucky or a passing archer or anything else really and this doesn't even address 'Way of the Ranger' that you'll want so you can learn charm, silence and other tricks.
Don't even dream of making an Archmage type character: all 4 magic skills, plus Lore, plus Willpower, plus Sourcery. Just getting those seven skills to level four would take 70 skill points! (Hope you didn't also want to make the occasional potion because you certainly don't have points for crafting)
Anyway I hope the skill system gets lot of attention before release. I'll be very disappointed if skill points are going to be that scarce.
