We both know he won't be buffed on his other numbers due to his strength on SR though, so he could stand to get an Energy increase.
Lee Sin -- No problem here.
Renekton -- He's strong at low level but has bad scaling and earlygame is over very quickly on Dominion. Maybe if he gained bonus Fury scaling by his champion level somehow, he'd be more viable here.
Shen -- Runs out of energy way too quickly in a fight. Even when "pacing" his skills he still falls quickly behind other tanks, in both damage and mitigation. Doesn't scale terribly well either. If he had more Energy, he'd be able to run the combos a lot more as necessary for this mode.
Shyvana -- The most viable of the 3 Fury champs, but that's not saying much as she won't be able to ult often even if she is bottom lane for more minions to punch. Like Tryndamere, I'd recommend double Fury on champion hits. She's severely lacking in top lane but is not unplayable.
Tryndamere -- I think if he gained double Fury on champion hits he'd be on par with other melees. Maybe a longer delay before it starts depleting, too. One of the worst champs on the map atm, you're basically punished if you try to go into a fight with 0 Fury but you have nothing to build it up on beforehand. He's a bit of a catch-22 as well, where you need crit chance to get fast fury, which grants crit chance itself, so you don't want more than 70%, which you probably already have from PD and IE and EC but still want more AS to make fury generation faster... yeah.
Zed -- Zed just runs out of energy instantly, can never have enough for the intended W and R jukes, and is often killed during his ult because he can't do anything. And that's not even going into his long CDs either. Poor guy is just really underpowered. I like his kit a lot, though.
Overall I think you could address Energy and Fury issues through the Crystal Scar Aura. The Fury is easy enough to address because all 3 Fury champs are underpowered due to bad scaling on it as a resource, but Energy might take a bit more thought as Akali and Lee Sin are fairly strong already.
This pretty much describes it all.
Akali and Lee Sin are fine.
Kennen has damage issues, so he spams to make up for this, then runs out of energy spamming.
Shen is and always has been clunky since his nerfs long ago, he gets really punished for trying to do what other tanks can do better.
Renekton only uses rage abilities when his ult is up, because that is the only reliable time he can build fury. The decay really hurts him.
Shyvana builds fury over time so she isn't that bad when it comes to her resources, but her kit is just naturally weak because of how kitable it is.
Tryndamere suffers from a similar issue that Renekton has and that it is incredibly difficult to build fury. Also, Frozen heart being so incredibly strong.
Zed, poor Zed. I got this guy, played a game with him then refunded him. Long CDs+Energy Issues+Low damage outside of his Ult make him atrocious to play.
