AFAIK each class has a hard and soft cap on AC. The hard cap is quite low and any ac worn beyond that is subject to diminished returns. The hard cap is different for different classes and the returns on ac beyond that hard cap (diminished returns) are different for each class. Warriors get the most ac returns on ac over the softcap for example.

Unless p99 is wildly different from live EQ (past specifically), secondary items specifically coded as a shield counts 1:1 for ac beyond the hard cap.

So yeah, shield ac is a lot more potent than all other sources for AC.

We use knights to tank half of tov, even my alt has tanked vindi.

Does shield of the dawn have the bladestopper graphic? If so, then this. FashionQuest > All. Other 2 shields look like garbage lo-res shit

Yep! SpikeQuest all the way.

Does AC on a secondary weapon count as "shield" AC?

No. The item must be tagged as a shield. A general rule of thumb is if you can bash with it, it's probably a shield. Something like Orb of the Infinite Void isn't a shield. I can't remember if you can bash with Orb the Infinite Void or not.

This is true. Whether you can bash is a very good indicator of whether or not the item provides ac coded as 'shield ac'. I do not know if this applies to paladin epic. SK/PAL epic weapons allow the wielder to bash while swinging them.

I suspect the paladin epic is not coded as a shield but rather as something uniquely different - but I have to admit that I do not know.

I don't think the SK epic has ac on it though? I dunno. I'd have to wiki google it.

Yeah Paladin and SK Epics are an exception to the rule. You are correct SK Epic does not have AC.

Troxx and DSM are agreeing too much in this thread, it's unnatural.

Paladin's and SK's don't tank flurries, they may bump when the 1st Warrior dies, that's bout it

Lol it is uncanny.

I was providing a damage example, it was the first one that popped into my head. 25 HP generally doesn't do anything against raid targets due to how hard they hit for.
