I'm getting towards that stage - I have near perfect ancient Aether walker and Shard of Hate, can't come across any kind of serpement sparker, and have decent TnTs also.
I run teleport, hydra, blizzard, shock pulse, armor, black hole. I skip magic weapon/familiar, but black hole for me adds a lot in the Tals setup (I use 6 piece) in terms of CC on top of frozen solid, plus I can add that stack from a distance without needing to teleport onto a mob (which I do sometimes anyway, it's fun).
The tals set is pretty good, and feels properly wizardly to me - squishy. As with any game, though, it's tough to find a good group. I've found a good crus and wd (EU) but good DHs aren't that common. And there are still many people simply leeching, in full xp setup in T6 rifts or in 35 grifts, but luckily if I join pubs with a 3 person group we simply kick out any and all leechers. Many people seem to think that they're entitled to just catapult to the top based on other peoples' play time, and it's easy to identify these people - who have an 80 hour DH with 500 paragon points and are playing a barb with craptastic gear and 500 paragon trying to leech in a pub.
In some sense, the match making system for pubs should be improved a lot too, to prevent this from happening. I hope this is worked on in the future as well.
