Cross-class ability choices

[Hundred]

The PLD would use Savage blade for the exact same effect however which is why Im saying it doesn't make sense to use.
Savage blade is 100 potency without a combo.
Skull sunder is 100 potency without a combo.
The enmity either generates without being used in a combo is the same.
If you are a PLD and use Savage blade outside of a combo you'll get the same enmity as using Skull Sunder in that situation.
If you want to get enmity faster without using Fast blade as a PLD then you can just hit Savage blade, it would give you the exact same effect as using a cross-classed Skull sunder in that situation. The two skills are copies of each other with the only differences being 1) animation and 2) The pre-requisite to count as a combo.
If you dont have heavy Swing then Skull sunder is always the same as using Savage Blade without Fast blade so then why would you use Skull sunder? You wouldn't.
If anything the reason PLD has skull sunder and WAR has Savage blade is just the mechanic they set up. The two skills are available to all classes and since both Jobs cross-class with the others main class they have access to it as a result of formality, they aren't useful.

The short answer is that these abilities are not for WAR/PLD to use.

It's a high threat move that another class could use (LNC/PUG for instance) if they wanted to act as a makeshift tank by spamming the move for some half decent threat generation (it has the same threat as spamming a 300 potency attack when used out of a combo).

They only reason PLD/WAR get the opposite move is a matter of completeness, as they get all of the cross class abilities provided by the other class. It serves no actual purpose for that class whatsoever.

As I understand it, it's very similar to Cure/Physick both are 2.5s, 400 pot heals with the exact same mana cost. A WHM or SCH has no use for those abilities because it's redundant with their own base cure.

What I was thinking was, it seems like they do vastly less threat when used out of a combo, so they must not have the emnity modifier when used outside of a combo. Turns out they do have the modifier, but they generate less emnity because they do half the damage without a combo. That was the error in my line of thinking.
