I agree that the memory system needs some tweaking
My problems with memory right now are:
-I don't like the 2 points per slot concept. The 1 point does nothing?! That is not satisfying. I would much rather have 1 points for 1 slot but have the abilities rebalanced so that much more of them take up two or more slots.
--OR give memory some other bonus in addition to the slots.
--OR give characters 3 ability points per level, which I think would be great to allow more flexibility. and the stat system needs a rework/rebalance anyway so it wouldn't hurt too bad
I really like someone else's idea of giving every ability an extended or bonus version by allocating an extra slot to it. That would be awesome
