Agreed. The new fire touch fills a different role than the old fire touch. It's pretty much death touch light now. Which is fine, if that's a niche that needs to be filled, so be it. But by no means is it still filling the old niche, which is now empty. Its defining characteristic was that it was a free attack that was 'paid for' by being short range and low power.
Even if harvesting was done by just running up and using something, that still leaves unfilled the hole for a free attack. Weak, short range, fine, but it feels like there should be something there.
