i've played patch (beta), elemental skills can have 30 sec duration and only uncastable for 6 seconds, meaning you can have armageddon+tornado around you for 30 seconds and also cast fissue/volcano etc
sorcs are too great... necros are ownage, assassins kick *4 hits is amazing versus bosses so far, paladins so-so , zons have interesting updates nothing godly pvp really though., and barb -_- nice
