I definitely won't play on S3 but I'm starting a Wiz team too, I have seen how it works. I have the same problem as you guys, which is, Tal Rasha seem to be VERY hard to drop. I have a complete Firebird set on all my characters, plenty of Vir's, some Delsere's, and... Maybe 4 pieces of Tal Rasha overall. That's going to be a long way.

Also i'm pretty sure that you know it, the #1 Paragon dude (non-season) is a multiboxer, and he uses that same setup at the moment (1x zDPS Crusader with all the XP stuff, and 3x Tal Rasha Wizards), and what he does all day is chaining GR41 in about 3 minutes.

He has a Twitch stream with a very bad image quality and it's in french (which doesn't bother me since I'm french), but you can see what he does and how.
