That was not a Pld specific change, so it hardly can be considered to be part of their "major adjustment." That would be no different than saying that Whm's got more utility out of casting Stoneskin on a Tank because the changes to Vit/Str. Yes they did, but no one's calling that a "major adjustment," nor does it actually do anything to change the utility of the move. The fact is that DV (and Stoneskin) are still being used the exact same way they were before, just with the added convenience of self-activation and a slightly higher shield. It's still being used in the same instances at the exact same, scripted, times as it was before.
Oath Swapping, as well, is simply more convenient. Before the change, good Pld's were prepping their swaps in time with Fight or Flight in order to get maximum potency. That hasn't changed. The only difference is that, as you said, we have a bit more flexibility in when the oath is swapped, and I do mean a bit, because it can only be delayed by a maximum of 2 GCD's before the first combo is lost and the total buffed potency is reduced. The thing is, assuming the Pld does their swap correctly and completes their full Fight or Flight rotation, then the total buffed potency is identical to what it was when a Pld did it correctly the old way. Nothing really changed, assuming you were doing it right before the "major adjustments" took place. Is it more convenient? Most definitely, but that's all it is. If you want to call that a "major adjustment," then that's your opinion, and you're welcome to it, but I don't see it that way. The fact that the actual utility of the move remains the same, and absolutely nothing about the way the job is played or utilized has changed, means that I don't consider any of those adjustments to be "major."
Regardless, I wasn't talking about any of those things in the first place. I was talking about Tp conservation, which has been a problem for Pld's since before 3.0. I never said that Pld didn't function in the 2.x content. I also didn't say anything about tank balancing in that content, either. That's a whole other can of worms that I'm not gonna get into. What I did say was that Pld's Tp was, and is, a problem, because it is unsustainable. In 2.5, and at maximum kit, a Pld could easily flat-line their Tp in any prolonged fight. That's not even contestable. The issue took a back seat for a bit when 3.0 was released because of new gear sets and leveling, but it reared it's ugly head again when Pld's reached cap. The Tp adjustments in 3.2 pushed it to the back seat once more, but, yet again, it's coming back as skill speeds start to increase. So, no. I do not consider SE to have taken a committed stance on fixing the problem, because they didn't fix it at all.
This also has nothing to do with bias. It's a documented fact. Pld had Tp issues as early as patch 2.5 (technically, before that, as Dreadwyrm gear became available in 2.4). SE did nothing, quite literally nothing, to fix those issues until patch 3.2. By comparison, Drk had Tp issues in 3.0. Blood Weapon was patched in 3.07. It only took them 2 months to respond to that problem. Whereas, it took them almost half a year to do the same for Pld. The same can be said for War. The fact that they actually did a redesign at all on War is pretty telling of their impressive commitment to that job, but it goes even further, because they did such a good job of it that they were able to build on it without causing any issues at all. In fact, all of the most recent War adjsutments have been nerfs because they did too good of a job ... Now compare that to Pld, who has had nothing but a series of patch jobs spanning all the way back to the 2.x in a poor attempt to throw band-aids over it's deficiencies. It's appropriate that you mention enmity as "never" being an issue, because most of the 2.x patches were actually enmity adjustments to various Pld moves. Seems to me like SE considered that an issue... Regardless, the only bias I see here is very clearly on SE's side of the table, only I was going to give them the benefit of the doubt and call it an oversight ...
