Until the stat overhauls are done, you only receive extremely minimal bonuses from stats (besides VIT/MND). They are literally only noticeable through parsing numbers, they aren't important enough to have a large impact on your current build. Your best bet for stats on gear at this point (up until the stat changes) would be +Attack & +Accuracy, as these stats can show visible results. As far as stat allocation, I imagine that once stat changes are in place, as per any DD your main concerns will be STR/DEX. It'll be another 4-6 months before anyone has solid evidence on how stats will properly work.
