No. Prot Palaldins were the weakest tank in MoP until HFC. You didn't see them around a whole lot in HM and BRF. They were strong in HFC, but not so much that they were ripping threat off of tanks 10 ilvls higher while simply performing their rotation on a single target. That's what's happening now. Our old Prot Pally is in another guild now, but came back on mumble to report that he co-tanks with a warrior and has to keep delaying his rotation to avoid overtaking the warriors threat on single target. That's insane. That also lines up with other reports I've been reading about Prot Pally DPS/threat.
