Basically, what if any stun or incapacitate applied to you WHILE you are casting has a 50% reduced duration. Before you flame this, think about it; it would accomplish several things:
For one, it would put some thought back into using stuns. Saving a Kidney Shot for when a Shaman uses Riptide or a totem instead of just mindlessly using your CC after the previous CC ends.
Two, it would allow interrupts to be the main source of interrupting again. A Priest channeling spells can still be interrupted, you just have to decide if your Pummel missed, whether it's worth using a DR'd stun to stop the cast.
Three, it gives healers and casters an incentive to cast -- as stun-protection -- if they know the enemy's actual interrupts are down. This alone would bring juking back into the meta-game.
And four, it would deepen the metagame and raise the skillcap. Instead of having "I interrupted his Nature", or "I juked his kick", you could also have "I casted his HoJ". It would create a way to lessen the impact of instant CC without making sweeping class changes to each individual stun. It's also important to note that based on the damage of instant casts usually being as high or higher than casted spells, this wouldn't cause casters to do more damage -- it would just promote more skilled play for both melee and casters.
