PLD abilities

[Ralvenom]

Royal Authority: Deals Damage... and nothing else.

I still fail to see the issue. As Launched said, Halone reduces enemy str. An attack that deals damage is perfectly acceptable for ANY CLASS, regardless of whether you like or not. Considering that PLD have block*, it balances out.

*Block & Storm's Path debuff both result in reduced dmg taken, but Block is constant. No WAR worth his/her salt keeps Storm's Path up all the time.

warrior can use vengeance at [snip]
Five times.

Divine Veil could be used at [snip]
4 times.

Let's be realistic here. There's very little reason to use vengeance at the start of a pull, since you don't need the 30% dmg reduction then. (You also probably wouldn't use it near the end of encounter either.) Likewise, you wouldn't use Divine Veil at start of pull, since you don't need the raid-wide shield then. Taking that into consideration, you basically have a viable opportunity to use either ability 3 times.

But you shouldn't really be comparing Vengeance and Divine Veil

I'm comparing them based on time. I thought that was kind of obvious, based on this sentence:

That's the same recast time as Vengeance (WAR skill).
