My Perfect Darkfall: Skill System

Today I start a new section in which I'll describe the changes I'd like to see so Darkfall becomes my perfect MMORPG. Those suggestions will probably imply a variation in Aventurine design philosophy and most likely big changes in core elements from Darkfall.
I'm gonna start with the skill system and I've made this quick draw to help me explain what I mean. I've already tried to explain it using how I hope the incoming Prestige Classes will be implemented. Now I'm gonna try it again in a different way.

As you can see I have first drawn how skills work in Darkfall now. This is a summarized version because in Combat Skills we really have several sets of skills per weapon and same with magic, but you know what I mean.
 In Darkfall there are 4 differents Skill Sets and the player is allowed to take all 4 of them. As seen below, I'd like to see more skills ans Skill Sets for starters, I believe Darkfall needs more non-combat skills and maybe few spells more to make the magic schools more autonomous. Then I'd like each Skill Set to be divided in 4 tiers (could be 3, could be 5) of increasing strength. Asuming only these two extra Skill Sets besides Combat, Magic and Crafting Skills Set, divided each in 4 tiers we have 20 tiers. In this example, the player could only choose 12 or 13 tiers. This way, a player could only master three Skill Sets but not all of them.
 If this systems was implemented, there would still be a lot of balancing work to do because the Combat Skill Set would be divided into 8 Weapon Sets, Archery and a common Combat Set with Rage, Throwing, Kick and so on, and Magic would be dividided into 10 Magic School Set and a common Magic Sets. Combat and Magic should be balanced with eachother, the same with each Crafting Set so noone can craft everything. But it's not that easy becasue Magic includes a lot of utility spells and buffs so it should also be balanced with Survival and Body Building Skill Sets.
With this system I want to promote variety and also a meaningful option. Some people say you can choose in the current Skill System but what does it matter if those choices haven't any real meaning or consequences? Well, what do you people think?


PS: Don't forget to take a look at the new models in the official Darkfall blog. The new Arthain and Demon Queen look amazing!
