Valiants are the heroes of Arathos, while the Dark Lords are the big baddies. All valiants should at least have a good fighting chance.

He's (Kane) usually partnered with a gang of rangers, though so I don't think he needs the skill CD badly.
The goal is to be able to use Kane efficiently without other rangers x) or at least two or his four forms. That's why I edited Gunslinger a little bit and Sharpshooter a lot to bring a new gameplay to this valiant (in fact, the Royal Huntsman could be good in other teams but noone takes the risk of doing him. I got Kane Arès in 400 gems invocation, I'm doing the tests atm)
