Yeah I agree that this is not a good idea. Memory is already the best stat. This would just make that even more of a priority.
The other stats feels sort of lackluster at the moment while we are on the topic.
why would I get a 5% damage boost when I could get a new skill instead?
Wit and memory are pretty much the only stats worth investing in right now. It's more efficient just to get the other stats on your equipment. I hope they alter this slightly.
Maybe I am overestimating the total number of skills they will have in the game but as it sits pumping memory and wit until you have enough skills to use non stop for 3 turns is the best route. Utility too stronk.
I disagree that Memory and Wits are the best stats. I believe an optimal build can often ignore them both.
I feel like memory is a more useful early game stat when the character level is low.
Towards the end of the current content (lvl 8) I get enough Memory from leveling and equipment that I prefer the 5% damage. For example, in my most recent run my level 8 character has 16 memory slots, 4 skills from gear, and 1 racial active. That's 21 abilities I can use (not to mention an unspeakable number of consumables), and I never spent a point into Memory. Since the amount of action points generated per turn doesn't increase, there is a saturation point where you have enough skills to keep you busy and additional Memory isn't very useful. The extra damage will always continue to be useful, however.
As-is, any early points I invested in Memory become a regret later. If new and better skills become available, that required more Memory, this would not be the case.
For Wits, I think there are 2 ways to do it. You can stack enough to always go first, or you ignore the stat entirely and accept going last. I have always ignored Wits. Since I will have my action after enemies, I essentially miss out on 1 turn per combat. However, I do extra damage for every action I do take, and for the action I used to start the fight. If a person spends 10 points in Wits to go first, that's +50% damage lost, and you have to keep sinking more points in it just to stay ahead of the increasing initiative levels of enemies. What's worse, is one never knows exactly how much Wits is needed to be faster than the next enemy, and if they are faster than you, those points are mostly wasted.
I do very much agree that higher tier abilities should require more points in the actual skill to learn them. As-is there are many skill schools that are 1-point wonders, just to gain access to the abilities. By having higher skill requirements for later abilities characters will actually become more specialized instead of placing 1 point into 3 schools and then stacking the rest of their points into the one Skill that has the passive they like best.
I don't particularly like the idea of higher level abilities having higher ability costs. They would have to be significantly different and/or better than abilities of lower memory cost for characters to even choose to use them. I feel like we would get a lot of redundancy too, and I don't think choosing between a 1-memory Fireball and a 2-memory Fireball+1 sounds very interesting.
