Why is Ruin a cross class skill?

[Nymphidel]

I have been wondering myself why ruin would be useful to any other classes/jobs. Good question. Low potency so why would anyone use it?

Same reason BLM can use Hawk's Eye.

Hawk's Eye -- Increases DEX by 15% and physical accuracy by 20%.

Poor design.

Yeah but how can that happen if they would have thought about it 1 second? It is nonsense...crossclass skills are a cool design but please some skills that are actually useful?

I wish they'd change the description on that. It says "increases physical accuracy" but what is actually does is just increase your accuracy stat, which does help blm land status effect spells (like sleep and binds). So it's not really "physical accuracy" but just accuracy as a whole. So it is useful
