Thanks for all the great Wizard discussion! I don't necessarily think channeling should be tied to DMO. There are already some great channeling builds that are showing promise on the PTR. I especially like the Firebird's EB Ignite one that Cratic showcased recently.
To help bring these channeling builds up in the next PTR patch, we'll be looking to increase the damage bonus on Deathwish and making it so that Etched Sigil also increases the damage of your Arcane Spenders (yes, that includes the channeled skill itself) while channeling. This is part of an effort to bring non-Archon builds to roughly the same power.
I know Archon is a heated topic amongst Wizards, so I want to say we will not be looking to nerf any of the current Archon builds. Instead, we're focusing on buffing non-Archon builds, like DMO Frozen Orb and these channeling builds, so that there is variety at that level.
The discussion and data we've been receiving has been great. We encourage you all to keep on testing as it helps us a lot. The best thing you can do for us right now is to keep on pushing Greater Rifts with all sorts of build on the PTR. Thanks again and have a great weekend!
