1. that 300% damage increase does not come in place of elemental damage on gear at all... So no.
2. Probably, eventually, yes. Look for the most realiably hitting skill and abuse it with things like force weapon and familiar to proc the other elements.
3. I think this was a bug that got fixed but i'm not sure. Afaik, TF is not supposed to proc elemental exposure anymore. Not sure about the meteors.
4. Not bad but you won't get any bonus against physical and poison...
5. No, it only works for the wizard elements which are fire, cold, arcane and lightning.
6. Arcane torrent might become more viable because of the defensive bonus you get, allowing you to possibly tank more hits while standing still to channel. Other options are probably frozen orb, disintegrate and ray of frost.
7. It will work but it might not be competetive with FB and the new set.
@lindviks: I'm 99% sure that refreshing the stacks means that it will refresh all of the elements.
