Is Warrior the weakest of the tanks?

[Hierro]

For daily roulettes, I believe WAR's the strongest. You have the most options to put out serious damage while remaining tanky. You can go into deliverance and never worry about what comes next because you have many cooldowns. You can even pop unchained while in defiance. If you're especially confident, you can use IR for 6 decimates. Zerk's shortened CD means it's now available for every pull. Basically, you can rely on WAR to give you fastest dungeons thanks to its top tier AoE/single target and competent tankiness.

I feel DRK is the tankiest, given you stay in grit and keep TBN on cooldown. But given the limitations for blood price and how that mixes with delirium, I suppose you have nothing better to do than to stay in grit anyways. This is all in the context of dungeon pulls.

For EX primals, according to fflogs the tank with the highest dps is WAR if you ignore the two PLDs on susano ex who were given single target balances by double ast.

If you played WAR in HW, you'll probably have an even easier time in SW. It no longer has mandatory buffs to shoehorn it into a raid spot (i.e. 100% uptime raid mitigation is gone and there are alternatives for slashing), but as long as you're semi-competent, you shouldn't have difficulty finding groups or clearing content.

The Defiance vs. Shield Oath debate has been floating around since ARR doesn't actually have any merit to it. Someone who is struggling on WAR is going to have an even worse of a time on PLD or DRK.

War's raid utility exists in how strong their cooldowns are. Look at fights like o3s and o4s, war makes an ideal tank for both these fights because of how perfectly their cooldowns line up. They do great damage, have great survival, and can change how mechanics are handled to make things easier for everyone. They may not outright have any x buff to others in party but that doesn't mean they have no utility. People are just parroting the whiners that don't know how to adapt and got too used to war being blatantly overpowered in heavensward.

Aside from trash mobs (and if your healer is good you probably won't) you never stay in grit past the first power slash (or two if it makes you more comfortable), as Blood Weapon just destroys Blood Price in effectiveness. Likewise, using TBN on CD isn't common outside of trash pulls as it is usually saved for tank busters or big AoEs (otherwise you'd be shooting yourself in the foot).

WAR is not the weakest. It has problems and isn't quite rewarding enough for its difficulty of mastery, but in its current state it's just a little undertuned rather than outright weak. DRK on the other hand has a broken mess of a kit that's both unfun* and the least effective of the three tanks.

*at least by my standards. I consider using one combo an entire fight to be excessively boring.

[Thaelon]

When someone says WAR is weakest they are just referring to raids, and truthfully the lack of raid utility with other classes bringing slash debuff now they are the "weakest". I do think War is more difficult then ever much more structures on rotation then ever before and much more them the other tanks! No tank is more penalized for getting caught in a mechanic with infuriate up.

WAR isn't weak in raid content either. It has the highest dps out of the three tanks and the biggest free mitigation kit. The cooldown rotation for V4S is easier when you have a WAR present, and it's a fairly solid MT choice for V3S.You might not have your own little parlour trick to impress your friends with, like a penchant for blowing bubbles or sprouting wings, but that's made up for with significant personal utility and quality of life features.

Burst dps is significantly easier to work with than sustained dps, because each individual globals matter less to you than it does to other jobs, as long as you don't do something silly like Berserk-IR when the boss is afk.

I think the initial memorisation of openers/Berserk might make someone who is completely new to mmos a bit nervous, but they seem more straightforward and more spammy than their HW variants. Basically, if you could do it in HW, you can definitely do it now.

Don't let people deter you from playing WAR.
It it perfectly fine in raid content.
Aside from party utility, they are very good in both dps, mitigation, and aggro though by only a small margin.
I started raiding as DRK this tier and once I cleared V1-3S on weeked one, I changed back to WAR and never regretted.
V3-4S are fights that work very very well with WAR and I certainly wouldn't want to bring my DRK instead (though it would be fine).

PLD still has a guaranteed spot in raid but in my opinion WAR is best for the second tank spot.

WAR has problems. It's not weak, but it doesn't stand out in any way or offer anything the other tanks don't.

I'd say it has more mitigation than any other tank. Not to mention Holmgang, arguably the best tank invuln due to the short CD. In O1s you can Holmgang both Twinbolt after Charybdis combos, in O2s you can holmgang every tankbuster, in O3s you can Holmgang every other Critical Hit, and in O4s you can cheese the tank swaps for Thunder and for Delta Attack, making the fight quite a bit easier.

Thanks, everyone! Quick question, if I did decide to start doing savage raids and such, will WAR not be useful? Is it solely because of the lack of utility or is it because they are squishier?

I felt more comfortable doing and clearing v4s as WAR than as DRK and DRK is considered my main... I'm not too good at war yet but until DRK has something changed (not sure what yet it just doesn't feel right) I'm enjoying WAR alot..
Go for it!
