Thanks Synapse, but I think you missed my point.
Block is Mitigation. Dodge and Parry are Avoidance.
Block doesn't count as "avoidance". A Block is you getting hit on the shield and you still take damage, but less because of your armor + block value. Like right now I have a Block Value of 981, so when I block I'm just mitigating 981 of a total hit. The hit is not avoided, but the damage it does is mitigated so I don't take as much damage.
For a warrior (and I believe pally too) the Block stats are not just about mitigation, but also about threat generation. The protection talent
Damage Shield is a part of my threat generation, especially when tanking groups. So I consider the % chance to block as well as Amount blocked both important stats for a warrior.
Your other point of the +Def on the Ony trinket, it gives me 14 actual defense.
- Increases chance to Dodge/Block/Parry by 0.56%
- Decreases chance to be hit and critically hit by 0.56%
Without that extra 0.56% my block rating would be in the 18.5% range. So at least I'm getting some block out of it.
Just don't see how the mitigation + avoidance stats come out to put the Ony trinket ahead of the Lavan one for my current setup.
