Yeah, I went gae bolg too. My drg is now i85, attack power of 498 (schweet). Gonna make you sad face real quick, the BiS stuff for war has none of the primal accessories in slot. Really sad too, given I've skipped the allagan ring a couple times in lieu of the vortex ring (which, as of last night, I've lost to EVERY other tank, and I was MT in each scenario, 4 drops now). My war is now i88, however, which is BALLIN. My advice, if you know in advance that you'll be offtanking in something like an hm primal, garuda ex, ultima normal, or even twintania, you'd be better focusing on having the boosted crit and determination over the extra parry, so get pretty much everything as you can so as you have options. Saddest part of it all is come 2.2, everything's probably gonna be outclassed quickly.
If you have some free time to do so, you'd benefit greatly from making a few crafted accessories with materia added. You'll lose a touch of vitality, but benefit from boosted parry rate AND strength, and if you wanted more crit and determination.
Gonna start leveling paladin next week. Hopefully I can work up the coinage for curtana +1 and forego the holy shield for now since I aquired an allagan shield last week. Already have all darklight and a bunch of allagan shit so it should be easy to have ready for combat use as soon as I hit 50. Just need to find motivation to get cnj/whm to 36 I think for stoneskin.
