Instead of accuracy here is what you need
for DPS: CRIT > DET Crit directly effects your ouput and burst and burst is everything in PVP. Just go down all your gears head to ring and check the stats and secondary stats.
For example: MCH
Your main stat is DEX (duh) whats next CRIT go down your gear and make see what you need to replace. ffxiv.ariyala.com is the best place! make sure you put i149>230 or whatever to get the biggest variety of gear and where you can get them that has crit got all crit? cool whats next: DETERMINATION Go down your gear again and see what you need to replace for to just see these stats: DEX / CRIT / DET (for MCH). Basically make a list of all the gear from ariyala that you need that has CRIT & DET (if its too hard to get you can go CRIT / skillspeed / accuracy(worst case sceneario) but crit is a MUST
