yes yes. this is a good question and i'd like to know as well.

well, with my GF tanking (I'm a mage) I've noticed Avenger's Shield avoiding my sheeps. But there's a catch, if she throws the shield right at the same time I'm casting the sheep, the mob will transform but receive a shield bounce and be freed. So if my observations are correct, the tank has to wait for the CC's to be in place before throwing his shield of awesomeness so they don't break. I might be wrong though, but that's what i've observed.

Avengers Shield will not break CC; provided the target is CC'd before the shield is cast.

Alrighty...but I swear I've seen it happen when it was cast after the CC. Maybe it's a latency issue?

In any case, I'll just try to be more careful about timing and perhaps run a test or two when I can.

If there is a bug involving it, Ive not seen it. Aside from accidentally casting it directly on a CC'd target (oops) I haven't seen it misbehave

I have actually had to go as far as to tell the Ret Pallies I run with to wait to repent after AS has gone out, just to make sure it does not break. There has to be a bug in there somewhere for the relationship between Repentance and Avenger's Shield.

It's clearly an attempt to plant seeds of mistrust between different pallie specs.

Yeah this is a matter of timing.

Avengers Shield will NOT break a CC'd target, so long as it is not the primary target of AS.

If you're a little too itchy on the trigger finger, and let that shield fly as your mage is casting, you might hit before the mob register's as CC'd.

So you can certainly launch a shield in there without having to guess and fret over which mobs your AS will happen to choose to bounce to, so long as the CC has securely landed and that your shield doesn't hit the CC'd mob as its main target.

I'm pretty sure Repentance IS broken by AS. I've had it happen when tanking and when using Repentance with another pally tank. That's the only CC I've seen broken by the bounces. I have seen sheep broken when it is cast after AS has been flying.

Repentance is bugged. I'm 100% sure of it. We tested this last night in Grim Batol to be sure. Every pull where AS could jump and break a Repentance'd character, it did. This has been the case since 4.1 and makes pulls difficult when you're running with multiple Paladins.
