I like the memory system but needing to put two points into the stat to get any benefit feels pretty bad, I would like one point to reward one skill slot. Currently, I find it very hard to justify taking skills that cost three memory slots and I'm not convinced it would be worth it even with my suggestion. Perhaps combining that with lowered memory slot requirements for a certain number of points put into Pyromancy (for example) would make everything feel better, and allow characters to specialise more.
