Depending on who we're comparing to I don't think I would agree, for example Warrior's skills slide right into place without much impact to damage meanwhile Paladin's do not and are situational tools that generally shouldn't be used except in those specific situations. In this way Warrior's ability to have the same duration at nearly half the cooldown while also relatively easily returning half or more of their HP makes it for no reason, imo, that Paladin's should be inferior, if any reason to that I think you might argue Paladin could justify a minor buff because of that. In most situations of skill or light planning- Warrior's is better. Of course Paladin does have a lot of other raid / situational tools, so I'm not sure I'd actually want to argue a buff, and Paladin's is still easier to use / work with, but if we just narrowed the window specifically on ability to get life back, cost of that, and anti-buster, between Warrior and Paladin I'd argue Paladin is the one that needs buffed not Warrior.
Compared to anything Dark Knight's anti-buster... sure it feels Dark Knight needs all the loves and no one else does.. lol, but to make Paladin's ability inferior- by the amount you suggested.. I feel is still pretty extreme. DRK's TBN doesn't hurt their DPS that much and is pretty powerful and versatile. If you said equal to Paladin's cooldown and dropped them to 1 health but then they could regain half health easily (on their own, while also being invlun), maybe that's closer to fair- but to say two minutes faster cooldown and the job can full heal off their anti-buster.. I don't think that's fair at all. If Paladin uses their move at full health sure they stay at full health but if they use it at quarter health they don't get it back just because they're under guard. Vampiric Hallowed Ground at 2 minutes shorter cooldown is significantly better than Hallowed Ground in many situations and is always better in any situation that the vampiric effect can function (since HG doesn't heal at all, and Paladin would generally have to go out of their way to heal in any meaningful way). Meanwhile the main beast is warrior hiding in the background laughing as we're trying to outpace Paladin as the measuring rod. Imo..
