Oh and please do tell me how is having 1 combat related skill per level instead of 2 going increase your characters fighting potential?
Or have you missed something important?
It's like you're suggesting a category system but don't even aknowledge that Survival and Social skills are real character advancement skills. They are!
Character progression in a RPG isn't entirely defined by combat related skill. In the current state of the game, a character gain 1 point from level 1 to 6, and then 2, and maybe more later. You have to choose whether you want to invest this point in any combat, social, or survival abilities.
What you suggest is gaining 1 point per category, which equals to 3 points per level minimum, effectively removing any kind of hard decision you had because you're gaining thrice as much points as you did from level 1 to 6 ( I'm nice here, I don't even account for Lone Wolf ).
In the current state of thing
"shall I invest in Way of the Warrior or Loremaster?"
What you suggest
"I will invest in WotW, Loremaster, and Barter"
Sure with 1point per level per category, you will be forced to wait a LOT before buying anything over rank 1 ( 2 levels woth of capitalizing then 3, 4, 5 ... ), removing your ability to actually invest in another combat related ability ( like WotW + Armor specialization, or two magic schools at once ). Actually, come to think of it, it even kind of kills your options.
