Crits don't work well in PvP, but if you insist...
What other equip you have? Pure Morrigane and 80 luk gives me total of 39 crit*2 (katar bonus), so there is 5 more crit from equip somewhere...anyway. You have armor and shoes free, best to use would be Gandora with ED card and Variant Shoes. Mid headgear...well, if you have slotted mid/lower headgear available, use that with Vanberk card, otherwise...I'd say Masquerade. In this case, there are no "easier equips", you either have the best or you're dead. Well, you are likely to be dead anyway if there's any good player against you.
Weapons...well, those are wrong. Bloody roar ignores def, but so do crits, so no reason why to use that except for suicide (you will have neither hitpoints, reductions or flee...). Speciality jur you have is also bad idea...all that stuff around balancing weapon atk and modifiers based on str would be too complex for you, so I'll just say that best would be probably slotted Infiltrator with Skel Soldier card.
Stats...well, needs a little balancing. A few points could be saved if you put your dex up to 9 and lower a bit agi. Get a few more points in vit.
