hey guys, first off im a lvl 17 shadow right now, and i play alot of pvp, screw quests haha anyway, im gonna get a pink-purple crystal soon, and i was wonderin which +41 boost i should go with; criticals, powers, or expertise? not too sure which would help me most, but i would likeas much damage as possible. so im guessing crits would do me good? but im not sure and i wanted to make sure before i spend my money so any info would be appreciated im pretty clueless:(
