The only numbers that should be included in your calculations of avoidance should be the ones from your paper doll. No more, no less.
Players make mistakes, and keeping up scorpid sting shouldn't be relied on when trying to check your uncrushability. _________________ Official thread killer
Regarding uncrushable/uncrittable, if you're uncrushable then whenever Holy Shield is up you can't be crit either. *However*, no one has perfect 100% uptime on Holy Shield due to lag, so 490 defense is absolutely mandatory, as a freak crushing blow due to HS lag may stress your healers, but a freak crit is likely a wipe.
