I've been building into spell crit for PvP lately but am having second thoughts about its usefulness. First of all, the impenetrable trait is becoming more prevelant. I'm worried that if an enemy's crit resist is too high, my attacks that do end up critting will do less damage that a regular attack.
Another issue is the resource cost. Not only am I sacrificing a mundus stone effect by using the thief, I also use inner light using up an ability on my bar. What do you guys think? Should I abandon crit?
