It totally does
Although, the MEVA from Turms pieces also give resistance to enfeebles, if I understand MEVA correctly.
It does, and Turms+1 have exceptionally high MEVA.
But you get even more if you use Runeist Coat +3, in addition to more HP, more MP, more VIT, more INT/MND, more def, more MDB.
It also grants Refresh+3 idle which is not game-breaking of course but it's quite a nice addition on some content, so much more than the Futhark's regen if you ask me.
Things might change in a few days once Futhark Coat +3 is released of course.
I wasn't promoting the idea of using a single tanking set for all content anyway. Or rather you can if you're an average RUN and frankly you're gonna be able to successfully tank every monster in the game regardless, but clearly you're a much better player than that and I'm sure you already deploy multiple tanking sets.
More focus on resist, more on HP, more on Inquartata/Parry or other stuff when you won't engage at all, etc.
Everybody can set a personal threshold somewhere according to how much they can be bothered with inventory issues and the annoyance of having to handle (and keep updated!) multiple sets in their LUAs.
My humble and possibly irrelevant opinion is that personally I favor other stuff over the nice "heal on parry" effect from Turms+1 hands which I find extremely useful in some situations as I explained above, but also hardly relevant in many others.
edit:
Oh and if someone is wondering which hands to use as an option with PDT/DT on the hands slot here's what comes to mind
1) PDT or DT augmented
Herculean Gloves. Anything else (VIT, MND, INT, w/e) is just icing on the cake. Cap on PDT is 5% with Fern, 3 or 4% for DT. Can go higher with Dark Matter of course but good luck with that.
2)
Kurys Gloves. Don't think they're viable with your set though, not enough DT. Slightly higher than average Meva (still much lower than Turms+1) and lovely enmity+9
3)
Runeist's gloves +3. Don't think these are viable for your set either, not enough PDT to cap at 50% (pre-Epeolatry of course). Still lower meva than Turms+1 but obviously higher than anything else, and good base stats. No enmity alas but that's really no concern I would say.
Might have done the math wrong but I think you need at least 6% total in your set in the hands slot to use Runeist+3 body in place of Futhark+1.
Again, all these things I just said hardly matter in the end because Futhark+3 body is gonna be released in a few days and that will likely change the scenario, supposing the stats increase will be good enough to bring it in line with Runeist+3, making the swap probably not worth it anymore.
