Technical reasons I would guess
Just saw a tank wearing 270 accessories for STR in Susano EX... People should stop with their sh** of everything must dps and just do their job, I don't recount how many healer just let us die in Susano EX and Lakshmi EX for the sake of their poor dps
I just find it confusing as a new player, that if you want to homogenize the accesories, then shouldn't even the lowest level combat accessories ( with no effect like exp bonus and stuff ) that give the attributes be locked behind roles as well ? What if - like I said - a healer wants to wear a VIT accessories to have more HP to survive mobs in dungeons JUST IN CASE; but a healer should wear MIND accessories right - to raise their damage and their healing potency.
If they don't lock old ones, or simply put both VIT and STR on fending accesories, tanks are gonna stick with i270 slaying accesories for the entire expansion.
I'm thinking it's a grace period, so people don't need to trash their current gear right when going into a new expansion.. but they should fix this issue at the latest when omega savage releases.
Every hit point beyond that which you need to survive is WASTED hit points. It's not at all surprising that once tanks have the survivability aspect covered, they'd do what they can to improve their DPS.
Tanks you see equipping STR and then dying are simply bad at it, not doing the wrong thing. A tank should only equip enough VIT to stay alive, and then equip STR beyond that point.
It's frankly bizarre that SE chose to revert to the STR = DPS, VIT = HP formula. What they SHOULD have done is make tank DPS dependent on VIT, and remove STR from the equation entirely - but failing that, the STR and VIT both give dps formula was decent enough.
Well simply because tank aren't dps, they're tank, that's why vit = vit and str = dps. That's not weird and not hard to understand.
Are they going to wear 270 accessories still when the ilvl will be 400+ at the end of stormblood? Seriously this is stupid. Like I said people take the dps too seriously. Just go play a dps job if you wanna dps as tank/heal
