Hex HAVE TO be banned, I don't know about others, but hex CC for 8s and don't break on damage. Also it always refresh after the effect expires, NO DR, the fetish lasts until the CD is refreshed, that's why is absurd.
Another thing to take in consideration is that diablo 3 have absurd RNG in spells, so a chain in stuns of frenzy (smite) + other warriors stuns to stun locked shouldn't be touched. I mean, it's not because of that that you have to ban a spell for example.
You can cap weapon dps and %crit damage if you like. Keep in mind that there are some interesting builds like hp regen barbs + UP + Warcry with hp regen, and kite for this kind of builds is essencial, so cap this stats may have a downside.
