I'm not sure Blizzard would go for it, because we likely have all the ranged pickup ability that they want to give us. It wasn't like they just forgot to include Dizzying Haze, the purposely pruned it (likely due to the redundancy) and extended Keg Smash, though I wouldn't mind if they pushed KS out to 30 yards. We're one of the most mobile tanks in the game, with a hard hitting AOE range pickup, at only 5 yards less than a DH/Paladin (3 targets only) I just don't know how much compromising Blizzard is going to on it considering how good of a job we already do at picking up adds. Honestly, the loss of Dizzying Haze probably hurts the PVP Brewmasters, as it was useful for spamming on people trying to get away in battlegrounds.
Fortunately, those rare occasions where you want to zap something like Iskar, CJL is hitting hard. (thanks Mistweavers) To give you an idea; at 810, Keg Smash is hitting for 131k, with a 6.5 second cooldown. CJL does 190k in 3.3 seconds of channeling with the same gear. If you've got nothing better to do while a boss is disengaged, zap away.
I agree that stagger should probably clear after combat. I just did a Heroic Violet Hold, and the healer died towards the end but I lived long enough to kill the boss. Then I died to stagger. Would it be possible to abuse it with Shadowmeld?
I'm saying Special Delivery is mechanically flawed. The damage or proc chance should scale up to reflect that if Blizzard wants it to remain a competitive talent choice. Don't get me wrong, it's neat to watch the first few times, and on a single target fight with 0 movement, it might be competitive with some damage/proc% tuning, especially if there are no harmless critters sitting 20 yards away that it decides to nuke.
As far as Niuzao, he's definitely a tuning issue. If they give him an AOE, I'd like to see something that radiates off of the little cloud that he already makes on the ground. Like Pigpen:
RJW only added Chi on 3 targets. It added nothing but damage ST, and it cost energy to do so. Xuen was damage, no extra functionality was used. Chi Torpedo healing? Come on, nobody outside of Mistweavers even noticed the minuscule healing it did, it was a damage ability. Also, stop calling it trivial damage. It's technically more DPS than Keg Smash, though they are close. Read your tooltips or perhaps, test it out.
