Tempered Will and Cover don't do enough to justify their cooldowns and restrictions. Having like two fights in the game made more convenient doesn't justify a 3 minute cooldown. Compare Holmgang or Plunge to Tempered Will - even taking the entire class kits into account, it's imbalanced. It's easy to make them useful in *all* fights and cover some holes in the paladin job as well.
Tempered Will - 90s cooldown; Current effects + removes TP cost for the duration. TP issues solved and has synergy with Shield Bash.
Cover - All Covered attacks will be blocked. Lets paladin use Shield Swipe as OT, makes Cover into a decent mitigation tool for the MT when paladin is OT.
Clemency is an ability that has a ridiculous amount of penalties attached to it. They're not really similar abilities, but look at how Inner Beast is designed - why doesn't it have a TP cost? Well, the justification seems to be that you pay for it with Wrath stacks. In return, you gain damage (highest in warrior's kit at the time of release), mitigation, and healing while spending no TP. For Clemency, you don't spend TP, but you give up 3 seconds of auto attacks and weapon skills, break combos, pay a high MP cost, can't move, can't block, and risk interruption. To top it off, it doesn't even scale with skill speed. In order for an ability to cost that much the result has to be worth it, and I don't think Clemency really is in raid fights. The main issue is its slow cast time, but I also think it shouldn't break combos like in 1.0. Additionally, blocking should be available during casts. So, rather than improving its effect I think they should reduce the costs.
Awareness should be a stat on gear - as an active skill, it's terrible.
It's true that skills don't necessarily have to be useful in every fight to be good, however when some of your skills are not useful in almost every fight, I think that's a problem. Same thing with Haymaker, One Ilm Punch, Lethargy, and other skills. When it comes to War/Drk, all of their niche stuff has very useful secondary effects that can be put to use all over the place. If there's no knockback or heavy/bind in a fight (not an uncommon occurrence), you can take Tempered Will off your hotbar and it'll make no difference.
