Cheating is not related only to Diablo, this is related to every game where people want to be on top of the boards (whatever board that is).

Some years ago, I was competing for rank #1 PvP in Dark Age of Camelot, reached #3 and was already called a cheater because I was using a secondary account to buff my main dude (which was legit). Then I figured out that some people competing for rank #1 were using hacks allowing to "fastwalk", etc.

But let's go back to Diablo III. I have been running some tests with a Fire Archon as main DPS, it's doable, here's a video below. It's only a GR60, I completed a GR65 after that but the video got cropped. Also, I imported my character in D3Planner so that you have the exact template and gear that I used in the video http://www.d3planner.com/230206621

Gear on the Wizard is ok, mostly ancient, no Caldesann's however. I tried to equip a Pain Enhancer gem for a try, but I'll probably go back to the "regular" Bane of the Stricken, it helps a lot on the Rift Guardian, which is the hardest part because it's very hard to keep Arcane Power up when you are spamming Arcane Torrent to reduce cooldown from Archon form.

There are probably a lot of adjustments to do, I will fix that when 2.4.1 goes live. The good news is that the Fire/Archon Wizard is pretty weak, but not as much as I anticipated. Also I might want to use a zDPS DH instead of a Monk.
