What has been stated before is that it in order to master something, you have to keep at it, which will make something else decay. You might be able to get to like 60 or 70 in all stats, but only dedicated weaponsmiths can get to 90 or 100 just like dedicated staffmen can get staff combat to 90 or 100.
Yah, can't really see fighting getting too diversified on any one game - maybe a secondary that is in the middle range and some dodging or parrying skill in addition to the main high-level weapon.
Being able to specialize in everything leads to bad game play and homogenization, IE Darkfall. Not even shooters are homogenized as bad as Darkfall was, you specialized depending on what gun you chose,. ( Rifle, Shotgun, Sniper Etc)
are there plans to have seperate skill point pools? Like, you can get so many skill points to be allocated to combat skills, some for crafting, some for harvesting?
Yes. This is already implemented. There is a soft cap for each skill group.

Separate pools = bad (in my opinion)
I think all skills should fall under the same soft cap, so you're either highly skilled in combat, highly skilled in crafting, or a jack-of-all-trades.
