My wizard used to be Frozen + Arcanist but still use demonic pet. Before demonic, some other pet I can't remember but something that was useful such as pathfinder or momentum or so. That demonic pet is edited since you can now edit pets with crystals these days (very very expensive though). Also be used to not have the but have 225% crit and 2× epic 75% crit.
This was my old warrior before I edited and I had him like that for ages. Also had crushing flames not come out or Arcanist wasn't nerfed , I would have added Arcanist + ascendant to my warrior to help and some potent element such as ice or poison . That old warrior I also used as a debuffer warrior for my floor climber.
When equivalence was changed a little bit, Regen was changed, prayer was nerfed and I add epiphany, this is what my old warrior would have looked like. I used elements slime at one point to speed up movement with shatter + charge . I also used resist to exploit the glitch/but when shrines have you 100k resist with 10k resist but also as survival since the build don't do DPS and I was lazy.
If Arcanist wasn't changed/nerfed or however you put it, I would have used Arcanist+ Ascendant warrior and that alone was too good.
As far as reduced CD, I tried it and it rapidly improved my farm rates since I could move around quicker with Charge and shatter.
Well now that I edited, I'm a bit proud. Albeit I lost many crystals but it's starting to pay off because I can farm quicker and less lag, even at floor 1000 no sweat. My warrior here does little DMG but that crushing flames is OP enough to help out and wizard only has a mediocre amount of DMG but still helps. I do remember experimenting with Haunting + aftermath + Frozen and Arcanist as well and it theoretically worked and actually worked, though not often so I changed my mind . That Arcanist did help me get to floor 1k farming easy but then crushing flames is where it's at.
Before even that, I used poison over Frozen when poison clouds used to be much more powerful by constantly ticking instead of only once. Floor 500+ farming was fairly easy though. Although I most of the time farmed at floor 200 but even more so due to dust crafting. Floor 400+ when it comes to pet feats.
