World Of Warcraft: Crowd Control and the Arena System

Tseric tells us some information about the up coming changes to Crowd Control:

The current plan is to reduce effectiveness of crowd control spells in Arena combat. I'm not sure at the moment if this will also carry over to battlegrounds, but it is a possibility.

What were looking into is having reduced duration of crowd control spells to prevent extended removal from combat. Outside of a PvP area such as arenas, spells will operate as normal, according to tooltip. Inside a PvP instance, a spell which may have had a 15 second duration will be reduced to a 10 or 5 second duration. The details of duration are not specific, I am merely using these numbers to illustrate the point and intent.

So, while we don't plan on disabling CC in Arenas, we do have intent to decrease its potential for extended incapacitation.
