No Sir, I'd rather play TERA then, don't like to be so limited.
I am a customer and I shop, I am looking in the game for something that would keep me playing, being limited and grind after reaching my goal? isn't my type of enjoyment.
That is all I can tell you.
Game is not a job and should never be one, game should be fun to spend time not a burden.
I think (Plus or lock) should depend on group skill.
For example:
Combat group 3 skills (for projectile weapons)
Resource and actions I would leave out. (no decay)
Crafting: 4
I would move woodcraft, masonry and wainwright to architecture and have 3.
