Deathfire touch any good?

For a while thunderlords was dominant and still kinda is. That was because the other keystones were kinda weak. I was all interested in DFT but always felt it was not very impactful vs thunderlords.

Riot have not made any changes with the keystones lately and seem to feel they are balanced.

Does anyone think DFT is in a good spot now?

I always thought it was kinda weak and that riot was holding off on buffing it because some mages like simply abused it while most mages hardly got anything out of it. I thought with the mage reworks they would be able to balance mages who abuse it and finally could buff it.

But that has not happened.

So again, does anyone think it is in a good spot?
