If WW was 100% useless, I really doubt that such a nerf would be made though. It may also be enough to be able to cast it twice before activating Archon as long as Archon handles the bulk of the cooldown. So even APoC may not be an issue. I could also use LL as a backup secondary instead of FN, it must be a skill that functions without my input while I'm in Archon form.See, but you're thinking like an Archon.
Keep in mind that the values I'm talking here aren't exactly your standard 1.4APS or CC. These are high end values that change everything, and not everyone will be walking around with them at decent dps levels.
Even if Archon couldn't be up all the time you could use that time to gather around mobs, though.
The issue is that CM/WW wizards have abused Wicked Wind at high attack speeds, and Blizzard is well aware that WW is ridiculously powerful at high attack speeds. They want to nerf both Archon and CM/WW wizards. Since Frost Nova was not nerfed, it's a good bet that WW is going to be hit hard to tone down CM/WW wizard. I'm expecting something like a 10x nerf for Wicked Wind, since that'll bring Wicked Wind down to the level of skills like Arcane Torrent and Meteor. This is why I'm saying plan on Wicked Wind being "useless" in the sense that you'll have superior options. I don't expect people to completely abandon Wicked Wind (being a stationary DoT), but I do anticipate spells like Living Lightning will probably provide superior performance as far as reducing cooldowns.
EDIT: And if it's not Wicked Wind that's hit by a nerf, that likely means CM is gonna altered/removed in such a way that makes reducing cooldowns more difficult. Either way I'd at least stay clear from Wicked Wind, and the most conservative bet would be to steer clear of both CM+Wicked Wind. Either way, I think talking about the future viability of Wicked Wind right now is a very bad idea.
