On my opinion, i like agi.
I'm making a battle smith, and i'm raising agi until 80-90. I have gotten 30 dex before, but i will get some more after, maybe 40-50 dex. The rest will be given to str. I'm an agi lover so i'm imaging my aspd plus berserker plus adrenaline rush and maybe an agi up OH MY GOSH

Agi is nice. It's what I nearly always get unless I'm experimenting with new ideas. The downside to agi is when you're either hit by attacks that never miss, or magic attacks.. Though, technically both of those could be fixed or at least helped with the correct cards..
