IIRC It was either Rift or Guild Wars 2 that required you to have a certain main stat before you could go into certain dungeons.

That could work in FFXIV.

Tanks can't enter Vault without XXX in Vitality.

I can't tell you the number of times I've seen players with ridiculously low ilvl gears in dungeons. I'm talking lvl 15 accessories in lvl 50 and 60 content.
