Thought I should expand upon "Pretty much anything is better than flashing steel." Apologies if my critique is offending you.
To the death forces you to target one enemy for an extended period of time. Useless on pala vs anything but the faction commander/dragon.
Extended period of time, a couple seconds? Its more for the guard generation vs. non commander mobs anyway. Hit something with it and use it as a guard generator while slaying everything else. Obviously most useful against high HP mobs. Behemeths, Pride Demons, Shield Dudes, and Commanders/Dragons. But, those are the mobs SS will have the most trouble with. More useful than Flashing Steel, IMO.
Warhorn serves little purpose on perilous aswell. If I wanted to generate support xp then id play a mage.
Like I mentioned, I'm not a huge fan of Warhorn. You obviously missed the point of me including it. Even it is more useful than flashing steel...
Charging bull was addressed in the video, prolonged charging = big stamina drain. Stamina passives and gear mitigates this, as stated aswell, though Looked Like It Hurt does not fully mitigate stamina drain since low level players have low crit chance. Having a second skill for free means you can charge till you run dry and you will be able to use another ability immediately afterwards.
Stamina is not an issue on the SS, at all. Even if it was, it would be a wasted point. It was on the Katari, and it still is on the SS. Doesn't matter how many promotions, much better ways to spend that point.
As for better passives, what is there? Gristly mutilation maybe, untouchable defense or turn the bolt. those are the only three which you can make a case for, two of which require two points to get.
Dance of Death(works on kills instead of one ability), Crippling Blows, Turn the Blade, Untouchable Defense, Unyielding, Terrifying Fury, Gristly Mutilation
All of those are more useful than upgraded charging bull.
