What should my materia be?

[Badbollen]

DH left side, STR right side

This game is hugely dps focused so generally if u can survive the tankbuster and auto after you have enough hp since no matter your hp you still need a heal after a tankbuster and you need to use a cooldown like shadow wall on it, when that requirement is met increasing dps is next, besides you already have max VIT on accessories so cant meld more and in that case we meld our dps mainstat STR

as far as scaling from what ive seen DH is king and then DET and SKS is better than Crit atm.

Tenacity is pretty decent and will only continue to become better, it's 1% for 200 so with 1000 TEN (what i have atm without TEN melds) i have a base 5% so while it doesnt scale as high for dps as the other TEN does more, it increase mitigation, damage and the amount you are healed for and is pretty popular for world prog on tanks. (This is from a raid prog viewpoint, farms and stuff i think we will meld whatever gives highest dps again)

atm i favour DH on left side

Like many raiders, I'm an agressive tank and care very much about my DPS contribution.
I'm fully aware DH is the better DPS substat but decided I'd go for Tenacity as the little extra mitigation is a decent trade off for the dps you lose.
Stacking 520 Tenacity from full left side melds is ~2.6% DPS increase and passive mitigation and self heals while 520 DH is ~3.33% DPS increase.
Not a big deal either way...

WTF really? Like, are you sure? That seems so useless to the point where I don't even see the point in bothering with melds.

Ah, screw it - I'ma go full skill speed! :'D
