isn't the charscale leg enchant the best for tanks? doesn't it have agi?
It's the only enchant by virtue of the fact that the alternative, str+crt, provides very little mitigation, as str-> parry rating you get from the DPS patch doesn't do nearly enough as the boatload of stamina you get on the patch alone, the agility is just gravy. Also if you want to get silly about this, the extra crit to help proc SD from the DPS patch on bears is just not worth losing stam and agi.
Some may ask why didn't they put a stam/dodge patch? Ask the devs, but my bear loves it.
