It appears my all-time favorite "purple rain" arcane torrent build isn't as sustainable as I hoped it would be past T4.

Might feel more viable when I get a couple of pieces of that Vyrs or Phoenix set (and their associated bonuses), but idk. The biggest issue was/is the need to stand still, but not being able to kill quickly enough to offset the damage coming in. Of course, I don't have and never have had any cool rings like SoJ and I'm going to have to start farming an int RoRG, so I have yet to find a proper ring upgrade. Upgrading is hard.
Will upgrading my Asheras pieces and rings fix my problem, or am I going to have to gut my build? I'm thinking maybe it'd be worth it to try to get a proper Mirrorball and spec'ing magic missile as my primary, which would at least allow me to kite and still deal lots of damage in situations where I can't simply afk channel Arcane Torrent.
When I used to play w/ my arcane wiz, I used the passive Temporal Flux to help w/ crowd control. Should give u more time to channel before they get too close. Try switching out arcane torrent for Disintegrate: Chaos Nexus. It pretty much gives u a laser beam that shoots out in a 360 angle. Clears out trash faster, I thought, and it's no slouch against elites either.
As for gear, yes a RRoG is pretty vital for a wiz, for pretty much every class, really. Try crafting some Aughild's, should help w/ elite DMG and mitigation. Get a harrington belt if u can, helps w/ burst. See if u can get the source Triumvirant, should help a bit w/ arcane DMG, or a mirror ball, of course.
