My DMO runs great but I don't want to be gimping myself. I know the top wizards run firebird archon but the bot ran that spec like crap with the stock trinity.
There are some other threads spread around about what people are using or having trouble with if you want to take a look.
In short, there are some issues with some of the Archon builds being 100% efficient that some people are reporting. I still feel that most of the Archon builds outperform the DMOrb builds.
I was running a FireBird Archon build with the Archon Combustion rune to about GR 65-70 in seasons before switching to a second Witch Doctor. Diablo III Character Planner
*Combustion rune to keep more ignite stacks up.
A lot of botters here are running the Tals/Vyr setup for Archon.
I would suggest taking a look at the leaderboards for the game and see what's trending. I am pretty sure it's still Firebird Archon.
