Why don't Tanks have attacks that can cleave multiple enemies?

[Xenosan]

For the Warrior to have physical AoE exclusively, considering the game life, is something I think is a bit overboard. I would like to see Steel Cyclone buff'd though now that WAR has Decimate. Some added tanking bonus. 1.0 Cyclone stunned enemies who were critical'd with it, and 100% of the damage delivered from that crit was absorbed as HP. Abyssal Drain for w/e reasons doesn't feel as satisfying as that old Cyclone did, I suppose it's due to the stun.

Hopefully PLD will get their fair reward, and if it isn't simple AoE attacks added to their kit, maybe something new like a stance or CD buff, similar to what the OP suggests, that turns some of the combo-Weapon Skills into AOEs. cone Savage Blade, cone Rage of Halone, radius Royal Authority, rectangle Goring. I'd enjoy that, won't happen though ; ;. Expect another dull 100 potency GCD AOE meant to be spammed ; ;

DRK's design of magical only AOE I think is a good definition for them. But if they did have a physical AOE, Spinning Slash would be a cool candidate - however it would work. Spinning Slash was a key component for DRK in early FFXI (they couldn't chain Light until learning Spinning Slash, which wasn't until lvl 66. During progression DRK 'BiS' never even touched Great Swords until 66 when that Weapon Skill was unlocked). So I like the idea of buffing XIV's Spinning Slash, in any way - aoe or something else, just for that nostalgia.

*inb4 the FFXI QQ, DRK would use Greatsword occasionally at low levels, like 30 an below,
