So, I've been thinking about the "options" you have when using your Paragon points at the moment, and I honestly don't think the options are equal(and the category names aren't ideal)
Utility is just a heap of "here's a bunch of random stats" and primary is 2 primary stats + the stats they couldn't fit anywhere else.
My idea is to add 2 more categories(Life Replenishment and Resource), and shuffle around a few of the stats:
Primary:
1 Strength
2 Intelligence
3 Dexterity
4 Vitality
(first 3 depend on class, because nobody would pick the others anyway, or have all 4 just to make it the same amount of options, even though it's the "point dump" category after everything else is capped)
Offense:
1 Attackspeed
2 Crit chance
3 Crit damage
4 Area Damage
Life:
1 Life on Hit
2 Life Regeneration
3 Life on Kill
4 Globe Effect Increase
Defense:
1 All Resist
2 Armor
3 Life%
4 Dodge(or something else, like CC reduction or elite damage reduction)
Utility:
1 Gold Find
2 Movement Speed
3 Pickup radius
4 Experience(either flat or %)
Resource:
1 Max resource
2 Resource cost reduction
3 Resource regeneration
4 Cooldown Reduction
Utility still has a similar problem, where MS and pickup radius actually have combat benefits, while the other 2 deal with improving the results of won fights(faster levelling/more gold).
Resource lets you choose how you want to deal with your resources(spend them quickly with CDR, have a bigger pool to work with, throw out cheaper spells).
Life moves life regeneration and LoH into a category where they actually make sense, as well as adding 2 more options for replenishing health.
Defense is the same except for the moved life regen and the added dodge/elite reduction/CC reduction.
Primary stat is essentially the same.
Offense has AoE instead of CDR, because AoE is quite clearly an offensive stat that directly increases your damage, whereas CDR deals more with the way you spend your resources.
I know this isn't the official forum(I posted this there as well, with a slightly different description), but I just wanted to hear other people's thoughts on the subject.
