TBC (Patch 2.0.1) reduced the CC cap to 12 seconds.

In PvP, Crowd Control effects will last no longer than 12 seconds instead of the full duration, with a chance of a heartbeat resist.

They did a lot of research for this on Scriptcraft back in the day.
Go read the Corecraft thread on this topic, it's enlightening.

In Vanilla, there WAS DR. But it pretty much worked like this:

Mage casts polymorph on player with full duration. There is a chance that polymorph will break instantly, but the chance is below 5% or so. It grows to about 50% at 7 seconds durations and slowly approaches 100% chance to break. So that wowwiki states. The duration in PvP is usualy between 7 and 15 seconds. I think it might even be no longer than 15 seconds, but I'd have to look it up again.
