Hey Akira,

To answer your first question, "290STR/280PIE/542ATK vs 293STR/260PIE/585 ATK," I would definitely go with the high ATK build. The +43 ATK add more damage to auto attack while at the same time increasing WS damage.

To answer your second question, "286STR/274PIE/585ATK vs 293STR/267PIE/585ATK," I think it's almost negligible damage difference. Your probably looking at 1-2 damage difference between the builds, but if I had to choose, I'd go with the 293 STR build.
