Stat/attribute points are very important for builds. One isn't enough for hybrid builds, especially not later in the game. One doesn't seem enough for pure builds either. Anything you do with 1 point feels like you did nothing at all.
I think I like that idea: What if you get 1 Primary Attribute Point every single level? That's a simple change which would make builds much more flexible.
Currently, odd-numbered points in a primary attribute grant the next stage in a bonus (AP cost reduction/Increased AP generation, etc), and even-numbered points only grant incremental improvement.
Because all the attributes do something useful, this means that you have to spread them really thinly. In the current build, Jahan requires you to spend many points into Speed just so he can get enough AP to do something – the high cost of his water spells means he has to spend half his turns saving AP – the INT cost reduction isn’t enough.
If he got a point every level instead of every two, I could make him more useful quicker instead of it taking like six levels. Yes, you’re doubling the points, but it also means that your character can grow faster, and is harder to screw up. More points also makes hybrid builds a bit more feasible.
