RDM: Does it get fun at 70?

[Tzain]

After hitting 66 I wanted to ask something about Red Mage and this seems one of the few Red Mage threads I could see that are active.
Am I the only one who feels that 'Impact' is a (no offense meant) waste of an ability?
The potency is only a touch above Jolt II.
It's available 50% of the time as a replacement to a spell that is the lowest priority to be cast (if verfire or verstone is up they are the better choice by a mile).
It requires using up a skill slot and learning new muscle memory for something that you cast (napkin math) 12% of the time if you're unlucky.
It's overly flashy with a particle effect that is way more intrusive than it has to be.
I admit, I'm a bad Red Mage and just dropped it off my bar. I would actually have preferred an extra role slot to this thing and I barely remember to use the role slots. I'm more likely to use Tether, and yes, I know I just reminded most of you that Tether was an ability in the first place (joking)

Side note: I think I'm going to start using Tether to annoy FC tanks when they try to to big pull.
