It will not go back down after you stop moving, however.
Forgive me but how is that known (to both of you) Has it been clarified somewhere?

Being forced to blow defensive cooldowns "just in case" we get interrupted hardly sounds encouraging.
We should react to what happens, not be forced to pre-empt and be screwed over if we get it wrong, or the opponent simply does it to force the cooldown.
Death's Embrace increased all your damage by 12%. Unless you're talking about the one that increases drain damage done per affliction debuff, which would still leave Drain Soul doing more DPS than SB (but not by very much), and also increasing Shadow Bite damage (assuming it will still work the same).
However, I agree that Affliction is nowhere near finished, and we will most likely see a few more significant changes before long.
I think they'll probably lower the casting penalty. That or it will mainly only be taken by affliction/pvp builds.
But I didn't take afflic pvp into account (probably because I don't pvp), but it'll be useful for them, too ... Drain Soul/Life, and los around a pillar, it's ticking half as fast but it's still ticking and you're los ... so, yeah, there's that.
forgive me for lack of blue-link, but there was clarification on this a while ago.
It only affects your casttime / channel time - ie, UA will take longer to cast, but will tick just as normal once it is up.
Since the channel speeds dots up - I would expect that to be fine, but the channel itself is your filler replacement, that is about 20-25% of your damage at present, and it will still be significant. So you would be losing out on your channel damage, while gaining nothing (pve).
PvP, I expect it to get nerfed, and ruin my pve utility :'(

If we lose a small portion of our damage only while moving, then I would happily take that as a sacrifice because it would be the first time we can use most of, if not all our toolset whle moving, and taking a far smaller hit on dps than we do currently.
What are we limited to currently on the move ? Fel Flame and depending on specs an occasional cooldown or proc.
