Frostworks vs. Spirit Tree

Does anyone have any strong affinity for Frostworks or Spirit Tree?

I have a Plant/Cold Controller that has one power (single-slotted) I can't decide what to use as. I was originally leaning towards Assault or Tactics, but I'm not sure I want the extra toggle as I don't like leaning on Heat Loss too heavily. My other pools give me less interesting options--Super Jump, Jump Kick or Flurry, Whirlwind, or Swift--and I don't think I want Snow Storm.

I'm currently trying to decide between Frostworks and Spirit Tree. Frostworks seems like it'd be more useful as something with only 1 slot, but I also don't see myself paying a great deal of attention to keeping people buffed, and I know that many characters don't benefit from it because the HP cap is so low. Spirit Tree simply doesn't impress me, especially with only 1 Heal for slotting.

Mind posting your build, would like to see what you're working with.

Could you also post a pic of your pet with ice shields lol

I'd choose Frostworks, simply because it leaves the recipient mobile. You can't get anything out of Spirit Tree unless everyone stays near it.

I read a post once that gave a detailed explanation of how Frostworks actually works, and the conclusion it gave was that the power is extremely poor. I can't find the post now, and I'm unsure how accurate it was, but it has kept me away from Frostworks so far.

I have limited experience with Spirit Tree and all I can say is it didn't really impress me.

IMO on Plant/Cold I'd be looking to skip both, but if I were going to take one it would be Spirit Tree.

Ok, found the post. The Frostwork discussion is a subsection in the second message on the page.
