In raids, you'll hardly notice the dearth since the Vengeance mechanic basically provides free threat. Yet in content where you're taking less damage (and thus can't stack Vengeance as reliably), you'll feel the pinch. Gearing can mitigate this to an extent, but it's a pain nonetheless.Prot paladins are the only tanking class that can't apply attack speed-slowing/physical damage-reducing debuffs on multiple targets at once like, say, a warrior can with a shout or Thunderclap. The trade-off, though, is we don't have a separate ability in our rotation that applies said debuffs, and we don't need to watch the debuffs and maintain them -- they're always there as a result of our normal rotation, which in the end is a fair trade.
