Greetings SE, I have observed a much lower enmity generation done by both PLD and WAR.
After one of the last patches where enmity generation was buffed, the amount of enmity generated was very high, often times hate could be held with little to no effort, and most players had generated less than 25% of the enmity meters. This however seems to have changed with the last update. I noticed enmity was being generated quicker by other players, and the meters were more commonly in the 35-40% range. Now obviously this isn't anywhere near the danger zone, but just something I noticed.
This isn't anywhere near 2.0 enmity generation, but it is indeed lower. I have asked a few other PLD/WAR that are used to tanking along side decked out ilvl88~90 DPS, and they too have noticed a difference in the amount of enmity generated.

So in short, PLD/WAR are not generating as much enmity as they technically should be, not anywhere near the danger zone, but the tanks I asked also do have ilvl 90~95 weapons, which means it could be more of an issue for lower ilvl tanks.
