2) after reaching certain skill level (lets say level 4 pyromancer), your low level fire skills could have 0 memory cost. This makes sense, because it would be really weird, that my allmighty fire mage who is capable of bringing down meteor from sky is not able to shoot small fire projectile at enemy.
So with massive investments into your chosen skill tree, you can become real master of that type of warfare, enabling you to use much more skills, but only from that tree. Which perfectly solves the above descripted problem of all mighty hybrid builds. If this restriction isn´t enought, we can introduce specialized talent (lets say "Fire attunement"?) to enable this.
Ideas?
Having nearly beat the alpha, I can honestly say that the memory system seems a bit strange. Once you access more advanced skills, they start to take up more memory. 3 to be exact. And they need a source point, of which you can only ever have 3 at a time. There's enough limiting factors on, granted, very powerful skills. I like this idea of the higher your skill at a school the lower the memory point cost because it does make sense. A master Aerothurge wouldn't be limited to a small pool of spells. They would have a large repertoire. It gives an incentive other than a small damage boost for investing farther into a school, but I think it should be set at breakpoints of 5. That way you have to commit 4 levels if you start with a point, 5 if you don't. Investing as much could reduce the memory cost of all skills in that tree by 1. Considering there are I believe 5-6 spells for low level skills in each class, and that the next tier cost 3 memory, it wouldn't make you too overpowered in my opinion.
