1) automatically expand memory slots with leveling up. The way it currently is, you can have lvl 20 character, but if you spend no points on memory, you will still have only 5 slots... which is quite meh and seriously no fun whatsoever. I would suggest, that characters get atleast 1 memory slot every 4-5 levels, this way you can have 8-10 slots at high level+few extra depending on your stat distribution (15 max with 20 memory?) This in my opinion sounds much better, as you can have no memory character, which must choose his main spells wisely, but is not too limited by this. Or you can have little more "hybrid" character, which gets much more spells in his skillbar, but has lower main stats as int and strength.
It keeps the basic idea intact, but won´t be so restricting that it might not even be fun anymore.
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?
This is actually what I was thinking, have it auto expand the memory as you level up and lower the memory cost as you upgrade that particular skills.
