popped up on the PTR in the first place

Here’s a little more insight into our thinking here (and why the changes even popped up on the PTR in the first place):

We have a few concerns with how Fire is playing out at the moment. Fire scales incredibly well with gear, and we’re worried that they’ll end up doing way too much damage in high end gear. However, we’re trying to avoid just nerfing Fire’s scaling, as that would unfairly hurt any Fire mage who ISN’T in high-end gear.

We’re also worried that Fire po wow is leaning too heavily on perfect cooldown usage. It’s awesome when a highly-skilled player is able to use all of their abilities to the fullest and be rewarded with a little extra damage. It’s significantly less awesome when failing to do so results in a massive loss of DPS. At the moment, Fire is extremely dependent on lining up all of your cooldowns (most notably Alter Time and Presence of Mind) to score massive Combustion damage. If you pull it off, you’re rewarded with a lot of damage. Mess it up, and your performance suffers dramatically. We’d like to tone down the differences between those high and low ends a bit.

We also think that Presence of Mind in particular is just too important to Fire right now. There’s really no choice in that tier – PoM is just too good compared to the other options. We want talents to be a choice.

Those are the issues we’d like to fix, and why the earlier changes hit the PTR to begin with. We may try other methods, or we may decide to just leave things alone for 5.4, but we do want to fix them.
