As the title says. Nothing about skill, just a nice number for a shadow priest. And a reason why mindspiking is much more effective at least in random bgs than playing too much with dots, since some ppl mean to argue about that playstyle but the dot damage is quite low and the damage done by mindspike is as i said much more effective.
My gear was average, there could be even higher crits and yeah i know that guy probably had no resilence but again, just a nice crit for spriest.
