It's fine man no need for apologies, it's a simple miss understanding that you were talking about Warrior, or any tank.
Anyway....
Going full Tenacity will cut down your Rdps by extreme levels and it doesn't provide a good alternative to your healers when they're only going to Off-GCD heal and only use GCD for AOE Heals/Regen, Solid Healers always avoid GCD heals as much as possible. Losing multiple thousands of Rdps for roughly 5-10k Healing difference won't change anything and merely kill the groups overall DPS. Gnb/Drk/War have their own self heals under GCDs and Off-Gcd which makes them overall good Main tanks, Pld cannot main tank since Clemency is useless except for prog to survive something you're learning, however Paladin is the best off tank at current raid tier. Paladin is 2nd to Gnb, has Veil, Cover and syncs with the Ninjas Trick Attack hardcore.
This stat has been considered of tests all the way back in 4.0 and remains a trash tier stat for being a weaker Det.
This game is ran by maths and no content is ever strong enough to warrant it (Yes including Ultimates). Speedrunning groups ALWAYS aim for max uptime and Crit farming which will completely overkill Tenacity build tanks trying to feed the healers more, the damage difference Ten build vs Crit Build is too huge I'm not even joking. Right now we adapt strategies to reduce movement for healers and remove any means of making the Blm move. The only healer who should priority over a Paladin is Whm if a very rare strategy calls for better overall group raid DPS, other than that you don't punish a GNB/DRK Main tank during their burst window on Trick Attacks and Paladin lacks Burst window which warrants a rare time Whm > Pld.
