The 10 are largely overlap, so clearly your higher level of play (which is more about the guild you find yourself in compared to the one im happy being in) doesn’t mean anything about your understanding of the game balance or how useful those things ret “brings” actually are in a 25 man raid.
So here is the list
Judgement of Wisdom / Light (brought by any paladins)
Kings (brought by any paladin, or 8% from drums)
Might (also brought by warriors)
Wisdom (also brought by shaman)
3% damage (also brought by BM or arcane mages, but you lose less DPS from an arcane mage not being fire than you lose from bringing a ret for this)
3% haste (also brought by moonkins, which deal more DPS than ret)
3% crit (also brought by ele shaman and assassination rogues, which both deal more DPS than ret)
Replenishment (also brought by shadow priests, frost mages, BM hunters, destro locks… Shadow + Destro are both higher DPS than ret)
Attack Power Debuff (also brought by druids, warlocks, and warriors)
And DSac OR Aura Mastery (both brought by other paladins, holy paladins get to bring both in one character slot).
So yeah, ret can bring a lot of things, but is the best choice for bringing none of them. It’s pretty rare that a well built 25 man raid is missing anything on this list that you’d particularly want a ret for over the other sources of the same effect. You generally need to be missing multiple in order for a ret to start looking appealing for buff coverage…
And hey, that’s exactly why before the buffs, there were FAR more fury warriors brought to cutting edge Algalon kills than ret paladins. It wasn’t even close, and even after the buffs, there are more fury warriors being brought even though ret has this supposed giant utility advantage.
Wrath was built to make most of it meaningless, which is why how much theoretical buff/debuff utility a class has is largely irrelevant as the vast majority of that list is covered by things you are probably already bringing.
They certainly aren’t useless, but their utility was certainly not strong enough to be 10-15% behind where Fury is on average and still expect groups to want them.
Vezax does worse than give melee none, they actually debuff melee while hyper buffing the caster DPS so each cast is almost 8x as powerful.
1/4 cost, 100% more damage, 1/2 cast time…
It’s very reasonable to ignore that fight when comparing classes because that is never repeated in the game to that degree.
