I don't understand why exactly you'd want to do that.
First of all you lose a lot of magic and channeling and honestly crit rate gain is useless. Your job as a wf is to purge, amp, cc, steal chi etc. Moreover, trust me, if you play wf in pk as LA, you'd rq your -40 channeling since you can't even pop blazing fast enough and you get 12'ed by eas.
There was a topic about HA/AA build as a wf which is also pretty useless.
Just stick to AA build. If you need def boost get a 3x def lvls+ phy dmg red or 4x def lvls weapon and you're good to go. If you really need the def and you can't stay alive get a might ring. But LA build as a wf is pretty stupid imo.
Full vit maybe?XD and tbh it only took me like 1-2 trys on most of my gear to get decent stats XD im full magic but most of my vit comes from gear thats like in the ss XD http://gyazo.com/380032984ebc1f60f61c5c5f0c17c53b XD
Meh was full vit as sage and still paper. No point unless u plan on trolling around in sage fox form.
Just my 2 cents.
