Many other jobs are getting old skills back...

Fracture should have been given the Goring Blade treatment and tacked onto Skull Sunder as a fourth combo with 10 beast gauge generation and a buff to it's initial damage to put it on par with Goring Blade. Then we would have BB for aggro, SE for self buff, SP for generation and Fracture as a strong DoT to manage. That would certainly be more interesting than the SE/SP/SP combo chain that's used ad nauseam nowadays.

DRK also needs something for their combos, as spamming SE combo 100% of the time gets rather boring.

This would probably have been too much of a nerf to warrior. They're not just going to give you a free huge dummy DPS increase like that, so the damage gained by a DOT as strong as Goring Blade would have to come from somewhere else. So let's say warriors are doing the same DPS they are now, but with an additional combo thrown into the mix - a combo that is worth a lot of your damage (as goring blade is).

1) Bad warriors are punished more - the opposite of SE's goals with 4.0
2) Warriors are punished more harshly when a boss is incompatible with DoTs (read: he jumps a lot, has a lot of adds, etc)
3) The warrior rotation becomes more complex, and I see many warriors complaining now that they're not rewarded enough for their rotation.

This whole argument about "lost" skills is weird because it's sometimes hard to tell whether someone wants the skills back for the power they had or for the gameplay implications. People will cite that paladin didn't lose anything it can't slot back. I'll contend that, Rampart aside, Conva/Provoke/Awareness were all burdens in 2.x and 3.x that prevented paladins from getting other more interesting/useful skills. Paladin just got stuck with them because every tank needs them, and that's why they were all crossclass in the first place. They weren't benefits, because even if paladin didn't have those skills, SOMEONE was going to, and they were going to be crossclassable. People complain about 1-2-3 gameplay from early paladin and that's because its skill slots were filled with ALL of the basic tanking shit and none of it was pushed on warrior. Paladin didn't lose anything because it had nothing to lose - it was a lazily designed job that was used to give skills to other, stronger jobs. Hell, even Flash was cross classable - why wasn't Overpower?

As for war/drk's lost stuff, I do agree with some things - Dark Knight's gameplay is crazy boring. I can't play that class because it triggers PTSD from 2.0 paladin. It could probably use a bit more defensive utility, so something like Delirium or Reprisal would be cool, but it'd have to be on a cooldown similar to other defensive utility. 3.0 Reprisal was an OP skill because it stacked with Storm's Path (another OP skill but whatever) and had crazy uptime. I'd like to see Low Blows come back (with a trait that gives them damage on Low Blow or something)

I don't think warrior needs any of its old stuff back. I've explained fracture above, but warrior is so inundated in defensive cooldowns that giving it foresight or bloodbath would be ridiculous.

Also, finally, this is from the OP:

Their removal makes no sense unless you just wanted ways to nerf those two classes without putting much effort into remaking the jobs.

This was EXACTLY their intention in Stormblood. They intended to bring WAR/DRK down and PLD up to try to level them all out. They actually got pretty close. Removing free DPS like Brutal Swing was part of that.
