Tempered Will used to be far more useful in 1.23, where there were so many enemies that caused knock-back (hence it's main use), but because of Beta tester complaints in phase 1, many mobs that formerly caused knockback (like vultures and boars) no longer do. Really, if they could make it so it makes the player immune to terminal knockback (ala, Titan, Demon Wall), but then give it a long cooldown, it would actually be very useful.

And Shield Swipe is very useful - yes it's somewhat random (as that it can only be used after blocking), but everytime it comes up I immediately use it, the Pacification effect on the enemy can be a great help. And Riot Blade is situational if you're spamming Flash a lot and need the MP recovery. I agree it could probably be given a better combo than just coming off Fast Blade.
