Discrepancy between health and focus increases

I was looking at the inate skills that increase health and focus and noticed that both give you +20 increase. If yo max out health, it becomes 120 and if you max out focus it becomes 20. Were there is a difference is how many points you have to put into health and focus to max out the skill. I have to spend 20 points in the healthy skill to get the 20 extra health and I have to spend 30 points to get the extra 20 health. I also have to go 4 levels deep to get the focus increase and only 2 levels to get the health increase.

Just another situation in a long line of situations it seems where mages seem to be second class citizens, and maybe not even that. And it doesn't seem to get better from release to release. In fact it gets worse.
