I've seen mixed opinions about going Seal Fate for raiding. A lot of online opinions say it's only really viable for phase 6 with AQ gear or better, but it also mentions having 30%+ crit unbuffed.

I recently hit R14. In my pve spec with a combination of pve gear & pvp gear I have 33.96% crit chance. Would it be much of a difference compared to combat daggers? Should I be worrying about which is more viable or will the difference be negligible?

Also, I play as horde, so maybe combat swords would still be better with Windfury. As R14 I could get the best daggers or swords. Any advice would be greatly appreciated.
