I find fore use for natures swiftness than nature's speed.
Nature's swiftness you can use to do your hardest hitting attack twice- quickly. Which is helpful in pvp or doing a boss or soloing.

Natures speed i've only found it helps in bosses and soloing. It may help a bit in pvp but since i only fight a cleric firned anymore i always end up dieing so i dont know how helpful it is or not.
