The Horrible Effect of Parry

[Arshes]

Of course, assuming he has a 5% parry chance (most mobs have base 5%, right?) the chance of that happening is really small. 1.953e-12 small:whistling:

:huh:

It's actually a very large chance. Each and every attack will have a 1/20 chance of triggering a parry. The attack roll is just one roll on a chart to get the outcome, the game doesn't roll them seperately for miss, dodge, block, parry, etc. Having a 20% miss chance for example doesn't overwrite also still having a 5% chance to be parried.

Now consider most melee with dual wields and instant attacks can pound out around 40-60 attacks a minute. (A feral cat due to 1.0 speed auto without the dual wield miss rate can put out around 80 attacks a minute :P). Thats basically 1/20 chance every second per melee person to trigger a parry. If you have 5 people in there doing it... pray for the tank.

Bosses also have instant attacks that they can put out on top of their auto attacks just like players on cooldowns. So if you're triggering parries as above and it has instants.. you can see a situation where the tank drops dead instantly no matter what the healers are doing. Regular attack, instant, regular attack again .5s later due to parry, Dead.

The biggest time this happens is when people are attacking large bosses from the side. They don't realize that even though it looks like they are behind the are actually not. Rogues and feral druids can tell easily because you go to hit a backstab or shred and receive the 'You are not behind your target' error. Warriors... well.. pick a smart rogue who backstabs to follow. :D
