I play a Druid, and my ring has +10% resource generation. but my spirit never regenerate on its own, i have to do basic damage to generate spriit. so how does this affix help my resource generation? is it when i hit an enemy i get 10% more spriit? because it sure doesnt go up on its own.
Anything you have that Generates Resource, that Affix should work with. Your Basic Attack Spirit Generation will increase by 10% in your example. There may be Passive Skills and Paragon that gives you Spirit on a Condition. These too would benefit from this Affix. For Barbarian for example, the 10% Resource Generation would benefit the Upgraded Leap Skill which gives you 40 Base Fury when you hit enemies. You would add 10% to this figure. Druid does NOT generate Spirit passively and the Affix does not give you Spirit Regeneration.
IMO - Druid and Barbarian need Passive ways for their Resource to increase. For Barbarian, all Direct Damage skills should generate Fury. Taking Damage should also generate Fury. For Druid, Spirit should regenerate over time in addition to its current sources.
you want 10% of 10mana/sec? if you want to have a version of resource generation build , you must have total above 34% on 2 rings, maybe you can get 14 mana/sec. its not worth if you at low level
you dont have a passive regeneration. 10% of 0 is still 0. so it increases your generation from generators by 10%. thats it 
Ok, i got a dolmen stone with 5.5% resource generation, but what good does it do for a druid that doesnt regnerate resource on its own, what passive can i have or spirit guide or whatever that can generate more spirit.
how else are they putting this affix to a druid if it cant generate resource?
i mean does it help if i use Maul, or any basic skill and it just generates more spirit like that? i still dont understand.
