Starting at 10 makes it easier to use attributes in formulas. I like how Memory works now. No way should it go back to "single points do nothing, two points gives you one slot".
But they probably could start that out at 3. It's probably done that way because it would look less aesthetically pleasing if it didn't match the others.
Hybrids are supposed to increase their versatility at the cost of power. Granted, it's less power in this game because of the need to spend into Memory as well as the usual attributes.
